PROBLEM TO BE SOLVED: To provide a transparent thermoplastic resin composition excellent in transparency and heat resistance. SOLUTION: This transparent thermoplastic resin composition consists of (A) 5-50 pts.wt. graft polymer obtained by polymerizing 90-50 wt.% aromatic vinyl-based monomer in the presence of 10-50 wt.% butadiene-based and/or acrylic rubbery polymer having 0.05-0.20μm weight-average particle diameter, having≥50% grafting ratio and also having pH<7, (B) 95-50 pts.wt. polycarbonate resin and (C) 0-45 pts.wt. (wherein, (A)+(B)+(C)=100 pts.wt.), and contains 1-10 pts.wt. butadiene-based and/or acrylic rubbery polymer based on 100 pts.wt. resin composition. COPYRIGHT: (C)2007,JPO&INPIT
