ABSTRACT OF THE DISCLOSURE Ester products useful as lubricants for structural resins are provided herein. The resins are derived from an aliphatic hydroxylic compound having 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups and a monocarboxylic acid selected from the group con- sisting of: (i) a mixed straight-chain aliphatic monocarboxylic acid obtained by the oxonization of a C22+.alpha.-olefin wherein at least 90% by weight of the olefins contain 22 or more carbon atoms, the mixed acid containing less than 30% by weight acids having fewer than 21 carbon atoms, less than 20% by weight acids having greater than 35 carbon atoms and 55% by weight or more C21-35 acids with the weight ratio of odd to even carbon content acids in the C21-35 range being between 1.5:1 and 10:1; and (ii) an .alpha.-alkyl branched aliphatic monocarboxylic acid having at least 25 carbon atoms obtained by the free radical addition of a short-chain aliphatic monocarboxylic acid having from 3 to 12 carbon atoms and an -olefin containing 22 to 100 carbon atoms. The esters of this aspect of this invention provide excellent internal- external lubrication for PVC homopolymers and copolymers.
