| abstract |
The present invention relates to a heat-resistant, high-strength acryl-based copolymer and an optical film including same, and more particularly, to an acryl-based copolymer polymerized to comprise: (1) an alkyl (meth)acrylate-based monomer; (2) a (meth)acrylate-based monomer including an aliphatic ring and/or an aromatic ring; and (3) a (meth)acrylamide-based monomer. The acryl-based copolymer of the present invention maintains transparency and has excellent heat resistance. Also, the optical film including a compounding resin that comprises the acryl-based copolymer has high transparency and heat resistance, and superior workability, adhesion, phase difference properties, and durability. |
