Provided is an acrylic copolymer comprising; an alkyl (meth)acrylate monomer; a monomer comprising a cyclic pendant structure; and a tert-butyl (meth)acrylate monomer and/or (meth)acrylamide monomer. Also provided is a resin composition comprising the same and an optical film and an IPS mode liquid crystal display device using the same.

Highly heat resistant and highly strong acrylic copolymer, a resin composition comprising the same and an optical film and an IPS mode liquid crystal display device comprising the same

The present invention relates to an acrylic copolymer having high heat resistance and high strength, and an optical film comprising the same, and more particularly, to an acrylic copolymer for optical films in which alkyl (meth)acrylate monomers; (meth)acrylate monomers comprising aromatic rings and/or aliphatic rings; and (meth)acrylamide monomers are included and polymerized. An acrylic copolymer according to the present invention is excellent in heat resistance while maintaining transparency. Further, an optical film comprising a compound resin including the acrylic copolymer has superior transparency and heat resistance and is excellent in formability, adhesion, retardation properties, and durability.

Acrylic copolymer with high heat resistance and high strength, and optical film comprising the same

The present invention relates to acryl-based copolymers including an alkyl(meth)acrylate-based monomer; a (meth)acrylate-based monomer containing an aromatic ring; and a maleimide-based monomer, a resin composition including the same, and an optical film prepared by using the same.
