US 2023/0144513 A1 · METHOD FOR PREPARING COPOLYMER, COPOLYMER PREPARED THEREFROM, AND THERMOPLASTIC RESIN COMPOSITION COMPRISING THE SAME

Abstract

The present disclosure relates to a method for preparing a copolymer, a copolymer prepared therefrom, and a thermoplastic resin composition including the copolymer. The method includes introducing and polymerizing an aromatic vinyl-based monomer, a vinyl cyan-based monomer, and an imide-based monomer, wherein the imide-based monomer is introduced at once in an amount of 1 wt % to 24 wt % before the start of polymerization, and is continuously introduced in an amount of 76 wt % to 99 wt % from the start of the polymerization.
