Definitions
- the invention relates to the use of dihydroxy fatty acids and / or dihydroxy polyfatty acids as an ionizable group bearing compound which is reactive towards isocyanates for the production of polyurethanes containing carboxy functions.
- the invention further relates to polyurethanes produced using hydroxy fatty acids and to a process for their preparation.
- the dihydroxy fatty acids which can be used in the context of the invention are known from DE-OS 33 18 596. From DE-OS 35 07 505 it is known to use polyether polyesters based on the dihydroxy fatty acids mentioned as a polyol component in the production of polyurethane. Here, however, the carboxylic acid function is esterified, so that ionizable carboxy functions are present neither in the polyol nor in the polyurethane produced therefrom. Accordingly, the dihydroxy fatty acids are not reacted with the isocyanates as free reactive components, but are used to produce a precursor, namely the polyether polyester.
- Dihydroxycarboxylic acids are generally known to the person skilled in the art as suitable hydrophilic building blocks for polyurethanes from earlier applications by the applicant, for example from DE-OS 38 27 378. This If they are specified in more detail, dihydroxycarboxylic acids have a relatively low C number and are therefore not derived from natural fatty acids. In addition, it should be noted that of the dihydroxycarboxylic acids mentioned in the literature, those are preferred, or are only described in examples, in which the carboxy group is sterically hindered, at least by a part of the molecule in the alpha position. In DE 2804609 suitable hydroxycarboxylic acids are mentioned and stated that similar acids with sterically hindered carboxy and free unhindered hydroxyl groups are also suitable. Sterically hindered hydroxycarboxylic acids with up to 12 carbon atoms in the alkyl radical are mentioned in GB 2104085.
- a dihydroxycarboxylic acid preferred in almost all relevant publications is the particularly strongly sterically hindered dimethylolpropionic acid (DMPA).
- DMPA dimethylolpropionic acid
- the reason for the preference of the DMPA is likely to be that the steric shielding of the carboxy group, caused by the methylol groups in the alpha position, tends to cause them to undergo far less side reactions, ie crosslinking, than the person skilled in the art has with a corresponding compound a less sterically protected acid group.
- the expert accepts some procedural disadvantages in the production of the polyurethanes.
- the DMPA is generally solid at the reaction temperature and therefore has to be comminuted beforehand and the reaction can only take place on the liquid / solid boundary surface, ie in a two-phase system.
- the hard segment character of the DMPA is conditional due to the relatively small molecular size with high functionality, also causes a relatively high viscosity of the polyurethane polymers or prepolymers and can also negatively influence their application properties, such as water resistance.
- the object of the invention is to provide polyurethane building blocks which perform the function of the hydroxycarboxylic acids known and used hitherto, without at the same time having the disadvantages described above.
- these building blocks should be available on the basis of natural raw materials.
- the property profile of polyurethane is to be improved by the use of these building blocks according to the invention and the production of the polyurethanes.
- the object was achieved by using dihydroxyfatty acids and / or dihydroxy polyfatty acids as an ionizable group-carrying compound which is reactive toward isocyanates for the production of polyurethanes containing carboxy functions.
- the dihydroxy fatty acids which can be used according to the invention can be prepared by epoxidizing esters of unsaturated fatty acids, reacting the epoxides with acid catalysis with an excess of an aliphatic diol and / or water with ring opening and, if appropriate, transesterification, and the reaction mixtures at temperatures between 20 ° C. and 60 ° C with Al alihydrox are added and then saponified at temperatures between 80 ° C and 110 ° C to the dihydroxy fatty acids.
- the dihydroxy fatty acids according to the invention are preferably derived from naturally occurring fatty acids. Therefore, they usually have an even number of carbon atoms in the main chain and are not branched. Those with a chain length of C1 to C26 are particularly suitable.
- natural fatty acids are mostly used as technical mixtures. These mixtures preferably contain a predominant part of oleic acid. They can also contain further saturated, monounsaturated and polyunsaturated fatty acids. In principle, mixtures of different chain lengths can also be used in the preparation of the dihydroxy fatty acids or dihydroxyalkoxy fatty acids which can be used according to the invention and which may also contain saturated portions or dihydroxyalkoxycarboxylic acids with double bonds.
- the dihydroxy fatty acids according to the invention are preferably derived from monounsaturated fatty acids.
- monounsaturated fatty acids for example, 9,10-dihydroxypalmitic acid, 9,10-dihydroxystearic acid and 13,14-dihydroxybehenic acid and their 10,9- and 14,13-isomers are preferred products for the purposes of the invention.
- monounsaturated fatty acids which after epoxidation with water or dialcohols (diols) e.g.
- oleic acid (9/10 octadecenoic acid) is preferred. Both cis and trans isomers of all the fatty acids mentioned are suitable.
- dihydroxy fatty acids derived from less common unsaturated fatty acids such as decyl-12-enoic acid, stilingic acid, dodecyl-9-enoic acid, ricinoleic acid, petroselinic acid, vaccenic acid, elaostearic acid, punicic acid, licanoic acid, parinaric acid, gadoleic acid, Arachidonic acid, 5-eicosenoic acid, 5-docosenoic acid, cetoleic acid, 5,13-docosadienoic acid and / or selacholeic acid.
- Dihydroxy fatty acids which have been prepared from isomerization products of naturally unsaturated fatty acids are also suitable.
- the dihydroxy fatty acids thus produced differ only in the position of the hydroxy or the hydroxyalkoxy groups in the molecule. They are generally in the form of mixtures.
- Naturally occurring fatty acids are preferred as starting components in the sense of natural raw materials in the present invention, but this does not mean that synthetically produced carboxylic acids with corresponding C numbers are not suitable.
- fatty acids are to be understood as carboxylic acids with a number of C atoms between 8 and 36, regardless of their gain.
- the hydroxyalkoxy radical of the dihydroxy fatty acids is derived from the diol which has been used for the ring opening of the epoxidized fatty acid derivative. Preference is given to dihydroxy fatty acids whose hydroxyalkoxy group is derived from preferably primary difunctional alcohols having up to 6 carbon atoms. Suitable diols are propanediol, butanediol, pentanediol and hexanediol, preferably 1,2-ethanediol, 1,4-butanediol and / or 1,6-hexanediol.
- polyethylene glycol, polypropylene glycol and / or polytetrahydrofuran diol and their mixed or graft polymerization products are particularly suitable as diol compounds. This applies in particular when these compounds each have a degree of polymerization of about 2 to 20 units.
- epoxidized carboxylic acid esters for example epoxidized fatty acid methyl, ethyl, propyl or glycerol esters with water and / or the diols from which the hydroxyalkoxy group is to be derived are reacted under ring opening and, if desired, esterification conditions.
- Known methods can be used for this. It is preferred to submit the diol and / or water provided for the reaction together with an acid catalyst, for example a strong mineral acid, and to add the epoxidized fatty acid derivative continuously or in portions at a reaction temperature between 80 ° C. and 120 ° C.
- the progress of the reaction can be monitored by titration of the residual epoxide content or by means of spectroscopic methods.
- the acidic catalyst is destroyed by neutralization.
- the resulting dihydroxy fatty acid esters can optionally be freed from excess alcohol by distillation.
- the saponification of the dihydroxy fatty acid esters to the dihydroxy fatty acids is usually carried out.
- the saponification is preferably carried out at temperatures between 40 ° C and 120 ° C in the presence of water with basic catalysis.
- Suitable bases are the hydroxides of the alkali and / or alkaline earth metals and tertiary amines.
- the dihydroxy fatty acids are obtained as salts (soaps) and can be reacted with strong acids, e.g. Hydrochloric acid or sulfuric acid can be won. It is possible to clean the reaction products by single or, if desired, multiple washing with water. In principle, it is also possible to split the esters, in particular the triglycerides, with water in the absence of catalysts.
- dihydroxy fatty acids are understood to mean both the ring opening products of epoxidized unsaturated fatty acids with water and the corresponding ring opening products with diols and their crosslinking products with further epoxy molecules.
- the ring opening products with diols can also be referred to more precisely as dihydroxyalkoxy fatty acids.
- the hydroxyl groups or the hydroxyalkoxy group are preferably separated from the carboxy group by at least 1, preferably at least 3, in particular at least 6, CH 2 units.
- the ring opening products mentioned can be used in an outstanding manner for the production of water-dispersible polyurethanes.

- the proportion of c), taking into account the amount and the hydrophilic properties of the other components, is preferably such that the resulting polyurethanes are themselves dispersible in water.
- An exact quantity is not possible here. If, for example, polyols are used as the starting component, which in themselves already have a relatively high hydrophilicity, it will not be necessary to use as much c) in order to obtain self-dispersible polyurethanes as if largely hydrophobic polyols were used as starting substances.
- the amount of c) required in each case can therefore only be given via the "self-dispersible" function.
