POLYCARBONATE RESIN COMPOSITION HAVING GOOD CLARITY, FLAME RETARDANCY AND SCRATCH RESISTANCE

摘要

PURPOSE: A polycarbonate resin composition is provided to secure the fire retardant property, the mobility, and the workability of the composition, and to use the composition for an interior and exterior decorative material of a vehicle. CONSTITUTION: A polycarbonate resin composition contains 100 parts of base resin by weight, and 1~50 parts of flame retardant by weight. The base resin includes 65~99wt% of polycarbonate resin, and 1~35wt% of (meth)acrylic acid ester based polymer with the weight average molecular weight of 5,000~30,000 grams per mol. The (meth)acrylic acid ester based polymer is produced by polymerizing 80~99wt% of methacrylic acid alkyl ester monomer, and 1~20wt% of monomer capable of radical polymerizing with the methacrylic acid alkyl ester monomer.
