PURPOSE:To obtain a resin compsn. high in light transmittance and excellent in light-scattering properties, heat resistance, mechanical characteristics, flame- retardance, etc., by compounding a polycarbonate resin with a specified amt. of a specific acrylic resin. CONSTITUTION:100 pts.wt. polycarbonate resin (e.g. Upilon E-2000F, a product of Mitsubishi Gas Chemical Co., Inc.) is compounded with 1-30 pts.wt. crosslinked acrylic resin beads which have a mean particle diameter of 1-20mum and are obtd. by the suspension polymn. of a monomer mixture comprising 100 pts.wt. noncrosslinking monomer component consisting of 50-100wt.% acrylic monomer, 0-50wt.% arom. vinyl monomer, and 0-20wt.% other vinyl monomers (e.g. methyl methacrylate) and 0.5-10 pts.wt. crosslinking monomer (e.g. allyl methacrylate). |
