Document Type and Number:
Japanese Patent JP4253779
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject flexible composition having a low modulus of elasticity and useful as a substitute for a flexible polyvinyl chloride resin by compounding a polyester block copolymer with a specific core-shell copolymer. SOLUTION: This composition is obtained by compounding (A) a polyester block copolymer with (B) a core-shell copolymer containing (i) a polymer prepared by carrying out an emulsion polymerization of (i) a simple substance of butyl acrylate or a mixture of the butyl acrylate with 2-ethylhexyl acrylate, an alkyl (meth)acrylate having a 1-4C alkyl group, a vinyl cyanide compound, a monoalkyl maleate represented by the formula (R is a 10-24C aliphatic hydrocarbon or a 10-24C aromatic hydrocarbon) and a cross-linking agent as a core and (ii) a polymer obtained by polymerizing an aromatic vinyl compound, the vinyl cyanide compound and the cross-linking agent as a shell in (90:10) to (20:80) weight ratio of the components A:B. Thereby, the flexible polyvinyl chloride resin, etc., can completely be substituted.
