PURPOSE:The title resin composition having a high light scattering property and a high transmittance and suitable as a material for lighting covers, obtained by adding a crosslinked polymer of a specified composition to a methyl methacrylate polymer. CONSTITUTION:10-90wt% alkyl methacrylate in which the alkyl is of 1-4C (e.g., methyl methacrylate) is mixed with 20-40wt% aromatic vinyl monomer (e.g., styrene) and 5-50wt% alkyl acrylate in which the alkyl is of 1-8C (e.g., butyl acrylate). 100pts.wt. obtained noncrosslinking monomer mixture is copolymerized with 0.3-3pts.wt. crosslinking monomer (e.g., allyl methacrylate) to produce a crosslinked polymer of a particle diameter of 30-300mu. 1-40pts.wt. obtained crosslinked polymer is added to 100pts.wt. methyl methacrylate polymer to obtain the purpose light-scattering acrylic resin composition. |
