<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition excellent in impact resistance, moldability, heat resistance, and dimensional properties by utilizing a recycled material of polyethylene terephthalate (PET) resin moldings. <P>SOLUTION: This thermoplastic resin composition is prepared by compounding (A) a crushed material of PET resin moldings, (B) a graft copolymer represented by an ABS resin and having a specific composition, (C) an AS resin having a specific composition and other copolymers, and (D) a polycarbonate resin having a specified mol.wt., the weights of (A), a rubbery polymer derived from (B), and (D) being 1-50 wt.%, 10-25 wt.%, and 0-20 wt.%, respectively, based on the total weight of (A)+(B)+(C)+(D), followed by melt kneading with a vacuum-vented extruder under a reduced pressure at a resin temperature in the range of 255-285°C. <P>COPYRIGHT: (C)2004,JPO</p> |
