Description

Stabilizer composition containing substituted hydrazine compound and method of use thereof

The invention described herein relates to stabilizer compositions for non-living organic materials. More particularly, the present invention relates to stabilizer compositions having certain substituted Antimony compounds and other additives, including plastics, that are used to stabilize the action of non-living organic materials against light, oxygen and/or heat, thereby improving the color, performance and/or handling of such materials.

The mechanical, chemical and/or aesthetic properties of non-living organic materials such as plastics and coating materials are known to be impaired by the effects of light, oxygen and heat. For such polymeric materials, this damage typically manifests as yellowing or other discoloration, cracking or embrittlement of the material, and/or loss of gloss. Additionally, the isopolymeric organic materials are subjected to elevated temperatures and pressures during processing into articles which can adversely affect the physical properties and/or characteristics and appearance of the finished articles made from such materials.

Therefore, such materials require the addition of various additive systems to them for processing and maintaining long-term stability to maintain desired service properties. A wide variety of materials are known in the industry for use as such additives and stabilizers. In many cases, a mixture of such additives is employed. For example, stabilizers are known to include sterically hindered amines such as hindered amine light stabilizers (HALS), ultraviolet (UV) light absorbers, and antioxidants.

Although a certain degree of stability of the organic material is achieved by the use of one or more of these classes of compounds with various other additives, the high concentration required for effective protection often results in undesirable changes in the properties of the material being stabilized and the phase. Capacitive problems, such compatibility problems include bleed, pulverization, and coating Layer and color change. Stabilizers such as antioxidants conventionally include sterically hindered phenols, aromatic amines, organic-phosphites/phosphonates and/or thioethers. However, the proper combination of stabilizers must be carefully selected based on the desired final properties of the final article.

For example, a large amount of 6-hydroxyl groups in the prior art An example of a stabilizer composition of an organic polymer of a ruthenium compound (including alpha-tocopherol) alone or in combination with other additives (e.g., phenol and/or organic-phosphite/phosphonate). In addition to its inherent safety (which can be used and generally considered safe ("GRAS")) and its suitable physical properties, alpha-tocopherol is an effective capture agent for oxy radicals. It is also highly reactive with less electrophilic groups such as alkyl groups, with hydroperoxides, excited states of ketones, ozone, hydrogen peroxide, nitrogen oxides, and other reactive species associated with oxidative damage. However, although it is considered to be an excellent treatment stabilizer and color stabilizer, it is inherently viscous and is a black amber oil known to cause discoloration of organic polymers. As described by Laermer and Zambetti in Alpha-Tocopherol (Vitamin E)-the Natural Antioxidant for Polyolefins, Journal of Plastic Film and Sheeting 1992 8:228-248,247, if the color of the polymer is not critical, the alpha-tocopherol is suitable. Stabilizer.

Other prior art references detail similar problems with the use of alpha-tocopherol in organic polymeric materials. U.S. Patent No. 4,806,580, the disclosure of which is incorporated herein by reference in its entirety to the extent that it is not suitable for the use of alpha-tocopherol to stabilize colorless plastics, either alone or in combination with other additives, as it causes discoloration.

US Patent No. 5,807,504 An anthraquinone derivative and a stabilizer mixture of an organic phosphite or phosphonate, but which is disadvantageous due to instability upon storage and incorporation into the material being stabilized.

6-hydroxyl detail in U.S. Patent No. 6,465,548 Bismuth compounds have not been widely used as antioxidants for stabilizing organic polymeric materials because they do not have to overcome significant coloration of such materials.

Therefore, stabilizer compositions for minimizing the effects of light, oxygen and/or heat in non-living organic materials require further improvement. Therefore, the color, performance and/or processing of the materials are specifically enhanced while permitting higher processing temperatures and/or shorter cooling times and faster exit speeds for higher speed molding or effective reduction of molding cycle time stability Compositions and processes will be a useful advance in the field and will be rapidly accepted in chemical additives and various industrial molding industries.

As set forth in detail below, the present inventors have discovered stabilizer compositions which enhance the properties and properties of non-living organic materials against the harmful effects of light, oxygen and/or heat, and the use of such compositions for reducing polyolefin articles The use of cycle time for various molding processes.

Instance

The following examples are provided to assist those skilled in the art to further understand certain embodiments of the invention. The examples are intended to be illustrative and not to limit the scope of the various embodiments of the invention.

As a fluidity scale, the melt index (hereinafter also referred to as MI) is mainly used industrially for the treatability of an intended organic polymer material or for indicating standard and quality control. When a high molecular weight polymer melted at a given temperature is extruded from a circular die of standard length and diameter by applying a load, MI shows the weight flow rate (unit: g) within 10 min and is used as Melt viscosity index. Among the high molecular weight polymers, polypropylene having a lower MI value has better stability during processing, and polypropylene having a larger MI value has poor stability during processing. Polymers whose values show a small change after repeated measurement of MI are considered to have a large MI retention effect and are superior in stability during processing.

When the additive is kneaded into an organic polymer material (for example, by multiple passes), the yellowing index (hereinafter also referred to as YI) is also widely used for evaluation. The scale of discoloration of valence polymer materials. The yellowing index (YI) is measured by a colorimeter, where a larger value means discoloration or color development during processing, and a smaller value means less coloration during processing and thus superiority.

The advantages and unexpected properties of the stabilizer compositions and processes provided by the present invention are now disclosed by reading the following examples in conjunction with the drawings.

Example 1

The rheological properties of the stabilized organic polymer composition of the stabilizer composition of the present invention were tested by multiple passes.

Figure 1A: The stabilizer composition of the present invention in the form of vitamin E acetate (0.15%) together with zinc stearate (0.05%) is dry blended with Profax 6301 polypropylene homopolymer (available from LyondellBasell Industries). And (B), and compared to polypropylene (A) which does not contain any stabilizer additive composition. The Killion single screw extruder was set to a 60 mesh screen, a 280 ° C melting temperature and a screw speed of 100 RPM. The blend was extruded 5 times (extrusion and re-extruding 4 times). Samples were collected after each pass and the melt index was determined. Samples of each pass were collected and tested for melt flow index on a Dynisco melt indexer according to ASTM D1238-10.

As indicated by corresponding Fig. 1A, the results show that the polypropylene sample containing no stabilizer composition (A) can be treated only twice, while the polypropylene material blended with 0.15% vitamin E acetate is extruded 4 times.

Figure IB: A polypropylene sample was prepared as described above and extruded in multiple passes. (A): no stabilizer additive; (B): 0.15% vitamin E acetate; (C): 0.15% vitamin E; (D): 0.075% vitamin E and 0.075% vitamin E acetate. Also sample all with stability additives and 0.05% zinc stearate Blending. As indicated in Figure 1B, Sample D showed better performance than expected based on Comparative Samples A, B or C.

Example 2

The mechanical properties of the organic material (as determined by % elongation at break) were measured to check how the organic material was affected by the treatment. As in Example 1, dry blending and combining the two formulations contained no stabilizer additive (B) or 0.15% vitamin E acetate and 0.05% zinc stearate (C). The composite was extruded and then collected and compression molded into 1/16" thick flakes. Sample (A) of untreated polypropylene was also compression molded into 1/16" flakes. The tensile sample was cut into a dog bone sample of type 5 (ASTM D638) using a punch. Samples were tested on a MTS tensile tester at a crosshead speed of 2"/min. All analyses used a median of five samples. Using untreated polypropylene as a baseline control, the combination with and without the stabilizer of the present invention was calculated. The elongation of the polypropylene sample of the material was kept at %.

As indicated in the corresponding Fig. 2, the sample (C) showed a significant improvement in elongation compared to the sample (B) as compared with the untreated polypropylene resin (A).

Example 3

The yellowing index of the organic polymer composition with or without the stabilizer composition was measured for evaluation of discoloration. Samples were prepared by dry blending prior art stabilizers or they were dry blended with low density polyethylene at equal concentrations according to the inventors. The compounding was carried out using a Killion single screw extruder set to a 60 mesh screen, a 250 ° C melting temperature and a screw speed of 100 RPM. The sample was re-extruded 4 times (5 times in total). Samples of the composite material for each pass were collected. Determination of yellowing index using the Greta Macbeth Color i7 spectrophotometer (ASTM E313). (A): no stabilizer additive; (B): 0.1% IRGANOX® 1010 phenolic antioxidant (available from BASF); (C): 0.1% CYANOX® 1790 phenolic antioxidant (available from Cytec Industries, Inc.) (D): 0.1% vitamin E acetate. All samples containing stabilizers also contained 0.05% zinc stearate.

As indicated in Figure 3, the yellowing index shows that samples (B) and (C) are more yellow than (D) (ie give more color to polyethylene), and the data for samples (B) and (C) are in lane 3. The number of times and the fifth pass increased significantly. The yellowing index of the control sample (A) (no stability additive) remained low because there was no stability additive to the color. Those skilled in the art will further understand and expect that the yellowing index of polyethylene samples stabilized only with vitamin E will be even greater than that of samples (B) and (C), as vitamin E is known to severely discolor the polymer matrix in the industry. Phenolic antioxidants such as IRGANOX® 1010 and CYANOX® 1790 reduce undesirable discoloration caused by the use of vitamin E as a stability additive.

Thus, the stabilizer compositions and processes of the present invention provide the advantages of accidental and superior to their stabilizer systems currently known and used. Together, these experiments show that the organic materials stabilized by the stabilizer system of the present invention have improved mechanical and rheological properties, and that the stabilizer compositions of the present invention do not impart adverse color characteristics to the materials to which they are added.
