    摘要: Partial esters of saturated, linear C.sub.22 -C.sub.34 -monocarboxylic acids with polyols containing at least 3 carbon atoms and at least 2 hydroxyl groups are provided. The partial esters contain on average at least 1 free hydroxyl group and are generally obtained as mixtures of partial esters of at least 2 of said C.sub.22 -C.sub.34 -monocaroxylic acids. Particularly contemplated are partial esters based on montanic acids. The partial esters exhibit excellent release effects and transparency properties when used as release agents for plastics based on PVC or PVC copolymers.

    摘要: Mixtures of light colored bis(C.sub.8 -C.sub.22 fatty acid) alkylene diamides, C.sub.8 -C.sub.22 fatty acid esters, and, if desired, metal soaps of C.sub.8 -C.sub.22 fatty acids can be obtained if, in a melt containing fatty acids with 8 to 22 carbon atoms, a part of the fatty acids are condensed to the corresponding fatty acid diamides with diamines of the general formula NH.sub.2 --R--NH.sub.2, in which R is a straight chain, branched, or cyclic alkylene group with 2 to 12 carbon atoms; a part of the fatty acids are esterified with fatty alcohols with 8 to 22 carbon atoms and/or multifunctional alkanols with 2 to 15 carbon atoms and 2 to 6 hydroxyl groups; and, if desired, a part of the fatty acids are converted to the corresponding metal soaps with basic compounds of divalent metals. The condensation with the diamines is carried out before the esterification of the fatty acids with fatty alcohols and/or multifunctional alkanols. The mixtures so obtained can be used as additives in plastics.
