PURPOSE: A thermoplastic resin composition is provided which is excellent in clarity, weatherproofing property, chemical-resistance, and impact-resistance. CONSTITUTION: A thermoplastic resin composition comprises 10-30 pts.wt. of an alkylacrylate rubber polymer latex having an average particle diameter of 2500-5000 angstrom and pH 5-10, 40-70 pts.wt. of an alkylester methacrylate compound or an alkylester acrylate compound, 10-30 pts.wt. of an aromatic vinyl compound such as styrene and alpha-methylstyrene, and 1-20 pts.wt. of vinylcyan compound such as acrylonitrile. The difference in refractive index between the alkylacrylate rubber polymer latex and the mixture of the other components is 0-0.004. |
