Abstract
The present invention relates to a method for producing a copolymer, the method for producing a copolymer including: step (S) for adding aromatic vinyl-based monomers substituted with alkyl groups and vinyl cyan-based monomers to perform polymerization in the presence of a polymerization initiator, wherein the vinyl cyan-based monomers are collectively added before initiation of the polymerization in step (S), monomer droplets are continuously divisionally added during the polymerization in step (S), and the monomer droplets contain part or all of the aromatic vinyl-based monomers substituted with alkyl groups, and relates to a copolymer produced therefrom, and a thermoplastic resin composition including the same.
