Abstract

The present invention provides a polycarbonate resin composition having improved chemical resistance and solvent resistance while maintaining the original impact resistance, heat resistance, and thermal stability of polycarbonate resins. The polycarbonate resin composition of the present invention contains 100 parts by weight of polycarbonate resin and 0.01 to 20 parts by weight of a specific alkylketene dimer, and is suitable for various chemicals or solvents such as hand creams and cleansers. Adhering to molded articles obtained from the resin composition can also suppress defects such as cracks.

Description

technical field [0001] The present invention relates to a polycarbonate resin composition, and more specifically, relates to a polycarbonate resin composition with improved resistance Pharmaceutical and solvent-resistant polycarbonate resin composition. Background technique [0002] Polycarbonate resin is a thermoplastic resin excellent in impact resistance, heat resistance, thermal stability, etc., and it is widely used in fields such as electrics, electronics, information technology equipment (ITE, information technology equipment), machinery, and automobiles. However, there are cases where various chemicals such as hand creams and cleansers or solvents adhere to molded products made of polycarbonate resins, causing cracks and other problems, and there is an urgent need for a polycarbonate resin that is excellent in chemical resistance and solvent resistance. polycarbonate resin to avoid such adverse conditions. [0003] On the other hand, the alkyl ketene dimer used in ...
