Engineering plastics compositions containing a wholly aromatic polyester

摘要

A thermoplastic resin composition comprising 100 parts by weight of two or more thermoplastic resins and 0.1 to 100 parts by weight of a polyester having the specific structure, the polyester being added to the thermoplastic resins, wherein a glass transition temperature is not less than 50 DEG C and/or a deflection temperature under load is not less than 70 DEG C. The present invention provides a high heat-resistant thermoplastic resin composition which is superior in mechanical physical properties and stress crack resistance.
