THERMOPLASTIC RESIN COMPOSITION AND LIGHT REFLECTOR

摘要

Disclosed is a thermoplastic resin composition for light reflectors, which contains a thermoplastic resin (A) and a vinyl polymer (B) which is different from the thermoplastic resin (A) and has a mass average molecular weight (Mw) determined by gel permeation chromatography using TSK-GEL GMHHR-H 7.8 × 300 as a column of not less than 600,000. The thermoplastic resin composition contains 0.1-10 parts by mass of the vinyl polymer (B) per 100 parts by mass of the thermoplastic resin (A).
