## Abstract

An acrylic copolymer with high heat-resistance is provided. The acrylic copolymer includes repeat units of a monomer of Formula (1) and repeat units of a methacrylic monomer derivative: wherein x is 1-3 and y is 0-3. The acrylic copolymer possesses high heat-resistance and low water absorptivity. The invention also provides a method for preparing the acrylic copolymer.
