POLYCARBONATE/POLYESTER RESIN COMPOSITIONS HAVING GOOD IMPACT, EXCELLENT FATIGUE PROPERTIES

摘要

Provided is a polycarbonate/polyester-based alloy resin composition which is high in flexural modulus and heat resistance and is excellent in impact resistance, fatigue resistance and chemical resistance. The alloy resin composition comprises 100 parts by weight of a resin composition which comprises 30-80 parts by weight of a thermoplastic polycarbonate resin and 20-70 parts by weight of a thermoplastic polyester resin; 0.5-20 parts by weight of a core-shell graft copolymer; and 0.3-10 parts by weight of a thermotropic liquid crystal aromatic polymer resin. Preferably, the thermotropic liquid crystal aromatic polymer resin is an aromatic polyester-based resin or an aromatic polyester amide-based resin.
