METHACRYLIC COPOLYMER, METHOD FOR PREPARING THE SAME AND METHACRYLIC RESIN COMPOSITION USING THEREOF

摘要

Disclosed herein is a methacrylic copolymer which is a polymer of a monomer mixture comprising about 20 to about 99.9 % by weight of a C6-20 aromatic or aliphatic methacrylate and about 0.1 to about 80 % by weight of a mono-functional unsaturated monomer. Because the methacrylic copolymer has a high refractive index of 1.495~1.59, when it is blended with polycarbonate resin, it is possible to obtain a methacrylic resin composition having improved compatibility without any other compatibilizer.
