DETERIORATION INHIBITOR, THERMOPLASTIC RESIN COMPOSITION, AND MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a deterioration inhibitor and a thermoplastic resin composition having an excellent deterioration controlling performance accompanying hydrolysis of a condensation type thermoplastic resin, and to provide a thermoplastic resin molding having excellent mechanical properties, a surface state or the like. SOLUTION: The deterioration inhibitor comprises a polyester containing an ethylenically unsaturated group, the inhibitor being used for a condensation type thermoplastic resin containing no ethylenically unsaturated group.
