POLYCARBONATE RESIN COMPOSITION

摘要

Disclosed is a polycarbonate resin a composition. The polycarbonate resin composition may simply and exactly improve appearance properties such as yellow index (Y. I), haze and the like, and thermal stability during a high-temperature process, and provide processability by reducing gas generation during molding, through provision of a relational formula of addition amounts of a hindered phenol-based compound and a phosphite-based compound which function as antioxidants when mixed with the polycarbonate resin.

主权项

1. A polycarbonate resin composition comprising a polycarbonate resin, a hindered phenol-based compound and a phosphite-based compound, wherein the polycarbonate resin composition comprises the hindered phenol-based compound and the phosphite-based compound in a content range satisfying Formula 1 below and Formula 2 below based on 100 parts by weight of the polycarbonate resin:
0.6≦y/(x+y)≦0.9  [Formula 1] 0.05≦x+y≦0.5  [Formula 2] wherein x is parts by weight of the hindered phenol-based compound and y is parts by weight of the phosphite-based compound.
