Impact-resistant blend compositions of polycarbonate and polyester resins

摘要

The present invention provides a resin composition containing the following components (1) and (2): (1) 100 parts by weight of a resin blend formed of an aromatic polycarbonate resin (A) in an amount of 40-80 wt. % and an aromatic polyester resin (B) in an amount of 60-20 wt. %; (2) 2-10 parts by weight of an epoxy-modified block polymer (G) or (H), wherein the epoxy-modified block polymer (G) is a polymer which is obtained by epoxidation of double bonds derived from the conjugated diene compound in a block copolymer (E) which comprises in the molecule a polymer block (C) predominantly comprising an aromatic vinyl compound and a polymer block (D) predominantly comprising a conjugated diene compound; and the epoxy-modified hydrogenated block polymer (H) is a polymer which is obtained by epoxidation of residual double bonds in a partially hydrogenated block polymer (F) which is formed by partial hydrogenation of double bonds derived from the conjugated diene compound in the above block copolymer (E).The present invention also provides a thin-walled molded product obtained by molding the resin composition.
