摘要：PURPOSE: An antioxidant composition with excellent anti-blocking property is provided to be used for processing a plastic film mixed with an antioxidant into products like a molded article and a pipe.CONSTITUTION: The antioxidant composition contains an antioxidant represented by the following formula(I), and metal salt of fatty acid having 4~18 carbons, wherein the weight percent of the antioxidant and the metal salt of the fatty acid is in a range of 100:0.1~100:200. R^1, R^2, R^4, and R^5 are a hydrogen atom, an alkyl group having 1~8 carbons, a cyclo alkyl group having 5~8 carbons, an alkylcyclo alkyl group having 6~12 carbons, an aralkyl group having 7~12 carbons, or a phenyl group. R^3 is a hydrogen atom and an alkyl group having 1~8 carbons. X is a single bond, sulfur atom, or -CHR^6- group(R^6 is a hydrogen atom, an alkyl group having 1~8 carbons, or a cyclo alkyl group having 5~8 carbons). A is an alkylene group having 2~8 carbons or *-COR^7(R^7 is a single bond or an alkylene group having 1~8 carbons). One of Y and Z is a hydroxyl group, an alkoxy group having 1~8 carbons, or an aralkyl oxy group having 7~12 carbons and the other is a hydrogen atom or an alkyl group having 1~8 carbons.漏 KIPO 2007
