200535188 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a filled olefin polymer composition and a filled olefin polymer concentrate having improved mechanical properties and scratch resistance. [Previous Technology] Industrial and automotive applications often utilize filled polymer systems to provide the required mechanical properties.

The preparation method and properties of the polymer -1 polymer material are known in 98346.doc 200535188. A suitable polybutene polymer can be catalyzed, for example, by W99 / 45043, by using Ziegler-Natta (WNatta), or "as described in the purchase 02/102811, # 由 butylene = metal Obtained by polymerization, the two disclosures are incorporated by reference into this dilute 1 = the polymer material preferably contains up to about 15 mol% of co-polymer B: or acrylic. The Ding Xin polymer material is more preferably having at least ㈣% by weight. The homopolymer of crystallinity (using wide-angle X-ray diffraction after 7 days) is more preferably about 45 / ° to about 70%, and most preferably about 55% to about 60%. The raw materials for the oxidized feminine tobacco polymer material and the non-emulsified olefin polymer material in the composition of gas: may be the same or different from each other. In the preparation of the oxidized thorium hydrocarbon polymer material, the second method is to dilute the smoke: together: the original :: first under an inert gas layer (preferably gas), and exposing it to high energy free light. The free radiation should have sufficient energy to penetrate into the bulk of the polymer material to the required extent. The free radiation may be in any form, but preferably includes electrons and gamma rays. More preferably, the electron has its own acceleration ㈣ = 5 °. To about 4, _ kilovolts of the electron generator. Satisfactory results are obtained with radiation doses of about to about 15 million rads (" Mrad ", preferably about G5 to about 90 rads. The term " rad " is generally defined as ,, Regardless of the source of the radon, the method described in the National Patent Case No. 5, G47,446 caused the amount of free energy to be absorbed per gram of radon material. Self-free: The absorbed energy is known by The conventional dosimeter test, one of Danma

A polymer film containing a radiation-sensitive dye is used as an energy absorption sensing member Z • 10- 98346.doc 200535188 measuring equipment. Therefore, the term " rad, " as used in this specification, means that in a dosimeter placed on the surface of the olefin polymer material to be fired, each gram of polymer film absorbs free radiation equal to 100 ergs. Amount, whether the material is in the form of a bed or a layer of particles, or a film, or a sheet. The irradiated olefin polymer material is then oxidized, which preferably proceeds in a series of steps. The first treatment step includes the presence of τ in the active oxygen (the first control of active oxygen is greater than about 0.0004% by volume but less Heat the irradiated polymer to a first temperature (about 15 vol%, preferably less than about 8 vol%, more preferably less than about 5 vol%, and most preferably from about 13 vol% to about 3.0 vol%) ( It is at least about but below the softening point of the polymer, preferably about hunger to about 14 generations, more preferably about hunger to about i 0 (TC 'and the best about thief to about order. As fast as possible (more than It is better to complete the heating to the required temperature in less than about 10 minutes. The polymer is then maintained at the selected temperature (generally about 5 to about 90 minutes) to improve the reaction awareness of oxygen with free radicals in the polymerization. The maintenance time can be determined by those skilled in the art, the nature of the raw materials, the degree of active oxygen used, the radiation dose and temperature. The maximum time is determined by the physical constraints of the fluidized bed. In the second processing step Medium 'in the presence of oxygen (the second controlled amount of oxygen is greater than about 0.004 body %% but less than about 15% by volume, preferably less than about 8% by volume, more preferably less than about 5% by volume, and most preferably from about i. 3% by volume to about 3.0% by volume of polymer heated by W To a second temperature (at least about pits but below the softening point of the polymer. The second temperature is preferably from about t to below the softening point of the polymer 'and above the first temperature of the first step. The polymerization is then carried out. The material is maintained at the selected temperature and oxygen concentration conditions of about 1G to about 3 minutes, preferably about 20 to about ⑽ minutes' to increase the chain-break rate and the chain fragments to form long-chain branches. 98346.doc 200535188 “Minimizing to a minimum” means minimizing the long-chain splitting time of ± +%. This dimension is determined by the same factors in the first processing step. Ting 4 _ The same factors are determined in the optional third step,你 你 # yL ^ Under the gas layer (preferably, the olefin polymer material is heated to the softening point of the third-temperature polymer under inertness (a few are lice)), and it is very difficult for her. But low Call the bell at this good appointment. If it runs for about 120 minutes, it will produce a more stable product than ^-. Xv ". If the polymer is to be stored Rather than use it immediately, or if you use: The inside is the highest position of the range as described above, it is better to use the + row dimerization = then under the inert gas layer (preferably nitrogen), discern from the two Alas, it takes about 10 minutes to reach the fourth temperature of about 7CTC in the cold part. It forms a stable intermediate in this way, and degrades in 1 step. "It is stored for a long time under extreme conditions without going into actual conditions." One of the preferred methods of processing is to operate in the presence of a first controlled amount of oxygen at a-temperature, and pass the lightly-treated feminine tobacco polymer through a 7-bed module in the presence of a second controlled amount of oxygen. At the second temperature, it is dropped as' passing the polymer through the second fluidized bed system 'and then under the nitrogen layer,' the first bed, and the inner part, maintain the polymer at the third temperature. In commercial operations, Che Yujia is a continuous process, which uses a separate dagger bed 'in the first two steps and a purge mixed bed in the third step. However, the process can also be performed in a batch fluidized bed using a fluidized gas stream heated to the temperature required for each processing step. Unlike some techniques (such as the melt extrusion method), the fluidized bed method does not require the irradiated polymer to be converted to the melt state and then re-solidified and crushed to the desired form. The fluidizing medium may be (eg, 98346.doc -12-200535188 such as) nitrogen or any other gas that is inert with respect to the present free radicals, such as argon, gas, and helium. The concentration of peroxide groups formed in the polymer can be controlled during the preparation of the irradiated polymer by changing the radiation dose and the amount of oxygen to which the polymer is exposed after the radiation. The oxygen content in the fluidized bed gas stream is controlled by adding dry filtered air to the inlet of the fluidized bed. Air must be continuously added to compensate for the oxygen consumed by the formation of peroxides in the polymer. Alternatively, the oxidized dilute polymer material can be prepared according to the following steps. In the first processing step, when a controlled amount of oxygen is added so that the olefin polymer is exposed therein, the raw material of the olefin polymer is treated with 0.01 to 10% by weight of an organic peroxide hair spray, and the amount of oxygen More than 4 volumes please.

But less than vol%, preferably less than 15 vol%, more preferably less than 8 vol% and most preferably 1. G vol% to 5.0 vol%; the temperature is at least 25. 〇 but below the softening point temperature of the polymer i 'is preferred. In a second treatment step, the polymer is then heated to the softening point temperature of the polymer. It is about 25% less, preferably from 1 (t) to less than the softening point temperature of the polymer, and the concentration is within the same range as the first treatment step. The total reaction time is usually at least ⑼ after oxygen treatment at f to 4j. . However, below this "do not treat the polymer at a softening point temperature" is M hours to about: hours' and treatment in an inert atmosphere (such as nitrogen) to stop any activity from the d group.
