BRANCHED (METH)ACRYLATE COPOLYMER WITH HIGH REFRACTIVE INDEX AND METHOD FOR PREPARING THEREOF
摘要
<p>Disclosed herein is a branched (meth)acrylate copolymer prepared by polymerizing a monomer mixture comprising (A) about 20 to about 99.999 % by weight of a (meth) aery late monomer having a refractive index higher than methyl methacrylate; (B) about 0 to about 79.999 % by weight of a mono-functional unsaturated monomer; and (C) about 0.001 to about 10 % by weight of a crosslinking monomer. The copolymer has a refractive index of about 1.495 to about 1.590.</p>
