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.

Stabilizer for chlorine-containing olefin polymers, a process for its

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.

Partial ester release agents for plastics

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.

Melt-phase synthesis of dibasic organo-lead compounds

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.

Synthesis of dibasic organo-lead compounds in melt phase

Triglycerides containing hydroxy fatty acid residues, of the type obtainable by hydrogenating epoxidized natural fats and oils, are used as lubricants for the molding of polyvinyl chloride or copolymers predominantly containing vinyl chloride, and are a replacement for hardened castor oil.
