Abstract
Abstract Polymeric light stabilizers are provided having at least one 2,2,6,6-tetraalkyl piperidyl group in the molecule and a molecular weight within the range from about 1000 to about 20,000, that are polymers of an unsaturated carboxylic acid ester selected from the group consisting of unsaturated cycloaliphatic mono-, di, and tri-carboxylic acid esters having from seven to about thirty carbon atoms; unsaturated branched-chain aliphatic di- and tri-carboxylic acid esters having from four to about thirty carbon atoms; sorbic acid ester, 3,8-nonadienyl acid ester, oleic acid ester, linolenic acid ester and ricinoleic acid ester; or copolymers of at least one thereof with another copolymerizable unsaturated monomer; and synthetic resin compositions having improved light stability comprising per 100 parts by weight of resin from 0.001 to 10 parts by weight of the polymeric light stabilizer.
