SURFACE HARDNESS IMPROVER, THERMOPLASTIC RESIN COMPOSITION, AND MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition containing a polycarbonate, capable of efficiently and inexpensively producing a molded product excellent in surface hardness and transparency, and to provide a molded product using the same.SOLUTION: A surface hardness improver contains a polymer (A) containing 5-80 mass% of an aromatic (meth)acrylate unit (a1) and 20-95 mass% of a methyl methacrylate unit (a2) and having a mass-average molecular weight of 5,000-30,000. The thermoplastic resin composition contains 5-60 mass% of the surface hardness improver and 40-95 mass% of a polycarbonate resin. The molded product is obtained by molding the thermoplastic resin composition.
