ACRYLIC COPOLYMER, AND OPTICAL FILM CONTAINING SAME

摘要

The present invention relates to a heat resistant acrylic copolymer with high strength, and an optical film containing the same, and more specifically, to a polymerized acrylic copolymer comprising: 1) an acryl (meth)acrylate-based monomer except a tert-butyl (meth)acrylate-based monomer; 2) a (meth)acrylate-based monomer containing an aliphatic ring and/or an aromatic ring; and 3) a tert-butyl (meth)acrylate-based monomer. The acrylic copolymer according to the present invention shows excellent heat resistance while maintaining transparency. In addition, the optical film containing a compounding resin containing the acrylic copolymer shows excellent transparency, heat resistance, excellent processability, adhesion, phase difference characteristics and durability.
