RESIN COMPOSITION FOR OPTICAL PART AND OPTICAL PART

摘要

PROBLEM TO BE SOLVED: To provide a resin composition useful as a molding material for optical parts having little optical axis deviation of an optical system by a temperature change and provide an optical part produced by molding the composition. SOLUTION: The resin composition for optical parts is composed of (A) 30-70 vol.% syndiotactic polystyrene resin or a resin composition comprising a syndiotactic polystyrene resin and a polyphenylene sulfide resin and (B) 70-30 vol.% inorganic fillers. The optical part is produced by molding the resin composition.
