PURPOSE: To provide a resin composition having improved light resistance, low volatility of the stabilizer, and high compatibility to polymers, by compounding a synthetic resin with a specific unsaturated carboxylic acid ester (co)polymer containing tetraalkylpiperidyl group. n CONSTITUTION: 100pts.wt. of a synthetic resin is compounded with 0.001W5pts. of a polymer of an unsaturated carboxylic acid ester selected from a 1W3-functional cyclic unsaturated carboxylic acid ester, a 2W3-functional carboxylic acid ester having unsaturated bond in the side chain, a sorbic acid ester, a 3,8-nonadienylic acid, ester, an oleic acid ester, a linoleic acid ester, and a ricinoleic acid ester, or a polymer or a copolymer having 2,2,6,6-tetraalkylpiperidyl group of formula (X is CH, etc.; R 1 is H or methyl; R 2 is H or alkyl), etc. and having a molecular weight of 1,000W20,000 and obtained by the copolymerization of an unsaturated carboxylic acid ester with a polymerizable unsaturated monomer at a molar ratio of 10:0W1:9. n COPYRIGHT: (C)1982,JPO&Japio |
