Abstract
Ester products useful as lubricants for structural resins are obtained by the reaction of mono- and polyfunctional alcohols with high molecular weight branched-chain aliphatic monocarboxylic acids. The 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 and .alpha.-olefins containing 22 or more carbon atoms. The esters of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.
Claims15
An ester product derived from an aliphatic hydroxylic compound having 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups and .alpha.-alkyl branched aliphatic monocarboxylic acids 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 .alpha.-olefin containing 22 to 100 carbon atoms.
A thermoplastic composition containing 0.1 to 5 parts per 100 parts resin of an internal-external lubricant ester derived from (a) an aliphatic hydroxylic compound having 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups and (b) .alpha.-alkyl branched aliphatic monocarboxylic acids having at least 25 carbon atoms obtained by the free radical addition of a short-chain aliphatic monocarboxylic acid having 3 to 6 carbon atoms and an .alpha.-olefin containing 22 to 100 carbon atoms.
