ABSTRACT:
Provided are a method of preparing a transparent copolymer resin by continuous bulk polymerization of a polymerization mixture obtained by adding a phenol-based antioxidant and/or a phosphate-based antioxidant, a chain transfer agent, and an organic peroxide initiator to a monomer mixture including a styrene monomer, an acrylate monomer, and an acrylonitrile monomer, and a transparent copolymer resin prepared by the method, having good chemical resistance, fluidity, and discoloration resistance.
