Abstract

Polycarbonate resin compositions are disclosed, comprising: (1) (A) a polycarbonate resin and (B) polyesterether elastomer, said elastomer composing of a bifunctional carboxylic acid component and a glycol component comprising polyalkylene glycol and ethylene glycol, or (2) the components (A) and (B), and (C) a rubber-like elastomer, or (3) the components (A) and (B), and (D) a polyester resin, or (4) the components (A), (B), (C) and (D). These compositions are excellent in solvent resistance and so forth, and further possess excellent physical and thermal properties characteristic of a polycarbonate resin. Thus the compositions are useful for use in production of industrial and electrical articles, such as a car bumper in the field of car industry.
