Polymeric thermoplastic composition based on polyphenylene ether and an impact-resistant vinyl aromatic copolymer.

摘要

A polymeric thermoplastic composition having an excellent balance of mechanical and thermal properties, improved impact-resistance and a good processability, comprising: <C1) a polyphenylene ether; <C2) an impact-resistant vinyl aromatic copolymer comprising a vinyl aromatic monomer and an acrylic monomer polymerized and grafted on a rubbery substrate having a (Tg) lower than 0 DEG C, and <C3) a compatibilizing agent consisting of a vinyl aromatic monomer and an ester of the (metha)acrylic acid block copolymer. r
