Sulfonated polyester resin compositions.

摘要

A polyester resin composition I which reduces or eliminates drawbacks derived from poor dispersibility of an aromatic polyester resin and a polyolefin resin in each other in the case of blending of both the components and which is capable of providing a molded article free from peeling of the surface layer and having excellent properties and capable of being formed into a composite material, which comprises a blend of (A) a specified aromatic polyester copolymer containing a metal sulfonate group, (B-I) a specified olefin copolymer and (C) an aromatic polyester resin. A polyester resin composition II which reduces or eliminates drawbacks derived from poor dispersibility of an aromatic polyester resin and a polyamide resin in each other in the case of blending of both the components and which is capable of providing a molded article free from peeling of the surface layer and having excellent properties, which comprises a blend of (A) a specified aromatic polyester copolymer containing a metal sulfonate group, (B-II) a polyamide resin and (C) an aromatic polyester resin.
