Abstract: 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.

Abstract: Mixed esters comprising the reaction product ofa) an aliphatic, cycloaliphatic and/or aromatic C.sub.2 -C.sub.22 -dicarboxylic acid containing up to 2 hydroxyl groups, or a mixture thereof;b) an aliphatic polyol containing from 3 to 6 hydroxyl groups or a mixture thereof; andc) an aliphatic C.sub.2 -C.sub.32 -monocarboxylic acid containing up to 2 hydroxyl groups, or a mixture thereof;wherein the molar ratio of components a) and b) is approximately n-1:n, wherein n is an integer of from 6 to 15, and component c) is selected so that at least one free hydroxyl group is present per molecule of the mixed ester, are useful as lubricants for the molding of thermoplastic plastics, especially polyvinyl chloride homopolymers or copolymers.

Abstract: Stabilizers for chlorine-containing olefin polymers containing Ca complexes of 1,3-diketones, hydrocarbon waxes and esters and/or partial esters of saturated, straight-chain C.sub.12 -C.sub.34 monocarboxylic acids, in conjunction with zinc salts of saturated, straight-chain C.sub.8 -C.sub.22 monocarboxylic acids and esters of phosphorous acid, provide the polymers with excellent properties in regard to processibility and temperature stability.

Abstract: 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.

Abstract: Powdered basic metal soaps having a composition corresponding to the formula (MO).sub.n.M(RCOO).sub.2, where MO represents CaO, ZnO, MgO, BaO, PbO, or a mixed oxide PbO/CaO, CaO/ZnO, BaO/CdO, or BaO/ZnO, M is one of the metals mentioned above, RCOO represents an anion of a fatty acid containing 8 to 34 carbon atoms, and n has a value of 0.2 to 2, may be obtained by reaction of powdered fatty acids with powdered metal oxides in the presence of small amounts of water, alcohol, and/or an acid at temperatures between ambient temperature and 100.degree. C. and under a pressure not greater than ambient. Preferably, there is continuous removal of water formed during the reaction, and the reaction mixture is present as free flowing particles throughout the reaction.

Abstract: Dibasic lead-fatty acid salts are synthesized in a melt reaction between plumbous oxide and fatty acids in the presence of magnesium, calcium, and/or aluminum compounds. The salts are useful as stabilizers for halogen-containing polymers.

Abstract: Dibasic lead-fatty acid salts and mixtures thereof with neutral lead-fatty acid salts are synthesized in a melt reaction using a free-hydroxyl organic compound as a catalyst/initiator. The resulting products are useful as stabilizers for halogen-containing polymers.
