Composition of polyester-block copolymer |
摘要 |
Disclosed herein is a composition of a polyester-block copolymer, comprising 5 to 80% by weight of at least one kind of graft-copolymer obtained by graft-copolymerizing 50 to 25 parts by weight of a monomeric mixture predominantly consisting essentially of styrene and methyl methacrylate and containing 0.01 to 3.0% by weight of a cross-linking agent with 50 to 75 parts by weight of a cross-linked elastomeric trunk polymer containing not less than 50% by weight of rubber like segment selected from the group consisting of butadiene unit and C4 to C10-alkyl acrylate units, and 0.01 to 3.0% by weight of a cross-linking agent, and 95 to 20% by weight of a polyester-block copolymer, the composition giving shaped articles of favorable superficial appearance even when processed by shape-forming under conditions of mixing and kneading of a relatively low degree.
