Abstract
Abstract Ester products useful as lubricants for structural resins are obtained by the reaction of mono- and polyfunctional alcohols with high molecular weight branched- and straight-chain aliphatic monocarboxylic acids obtained from alpha -olefins containing 22 or more carbon atoms. High molecular weight acids useful for the preparation of the present esters are obtained by the free radical addition of a short-chain monocarboxylic acid to the C22+ olefin or by ozonization of the C22+ olefin. The esters of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A thermoplastic polyvinylchloride homopolymer or copolymer resin containing 0.1 to 5 parts per 100 parts resin of an internal-external lubricant ester derived from an aliphatic hydroxylic compound containing from 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups and a mixed straight-chain aliphatic monocarboxylic acid obtained by the ozonization of C 22 + α-olefins wherein at least 90% by weight of the olefins contain 22 or more carbon atoms, said mixed acid containing less than 30 % by weight acids having fewer than 21 carbon atoms, less than 20 % acids having greater than 35 carbon atoms and 55% by weight or more C 21-35 acids with the weight ratio of odd to even carbon content acids in the C 21-35 range being between 1.5:1 and 10.1.
Claim 2
Dependent Claim
