<p>PURPOSE: An acrylic copolymer is provided to have excellent transparency and heat resistance, and to be manufactured without generating reaction byproducts. CONSTITUTION: An acrylic copolymer has a repeating unit represented by chemical formula 1, and contains 0-1 ppm of a (meth)acrylic acid unit, glutaric acid anhydride unit, or a mixture thereof, in the chain thereof. In the chemical formula 1, each of R1, R2, and R3 is independently hydrogen, or methyl group, each of R4 and R5 is independently linear or branched C1-12 alkyl group, C1-6 alkyl substituted or non-substituted C3-12 cycloalkyl group, or C1-12 alkyl-substituted or unsubstituted C6-30 aryl group; and m:n is 0:100-99:1.</p> |
