The present invention relates to a heat resistant high strength acrylic copolymer, and an optical film comprising the same, and more particularly, 1) an alkyl (meth) acrylate monomer; 2) (meth) acrylate monomers including aliphatic rings and / or aromatic rings; And 3) a polymerized acrylic copolymer including a (meth) acrylamide monomer. The acrylic copolymer according to the present invention is excellent in heat resistance while maintaining transparency. In addition, the optical film including the compounding resin containing the acrylic copolymer is excellent in transparency and heat resistance, and excellent in workability, adhesion, retardation characteristics and durability. |
