(METH)ACRYLIC COPOLYMER, METHOD FOR PREPARING THE SAME AND ARTICLE COMPRISING THE SAME

摘要

A (meta)acrylic copolymer of the present invention is a copolymer of a monomer mixture comprising a monofunctional unsaturated monomer and a phosphorus based (meta)acrylic monomer represented by chemical formula 1. The (meta)acrylic copolymer improves refractive index and has excellent flame retardant, transparency, scratch resistance and environmental performance. In chemical formula 1, R_1 is a hydrogen atom or a methyl group. R_2 is a substituted or non-substituted hydrocarbon group of C1-C20. R_3 and R_4 are a substituted or non-substituted cyclic hydrocarbon group of C6-C20, respectively. m is an integer of 1-10. And n is an integer of 0-5.
