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 C.sub.22.sub.+ olefin or by ozonization of the C.sub.22.sub.+ olefin. The esters of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.
