Method for preparing core-shell copolymer, core-shell copolymer prepared therefrom and resin composition including the same

A method for preparing a core-shell copolymer includes polymerizing a core by polymerizing 70 to 90 parts by weight of a methyl (meth)acrylate monomer and 1 part to 20 parts by weight of a C2-C12 alkyl (meth)acrylate monomer, based on 100 parts by weight of the total content of the monomer; at a poi...

Zusammenfassung:	A method for preparing a core-shell copolymer includes polymerizing a core by polymerizing 70 to 90 parts by weight of a methyl (meth)acrylate monomer and 1 part to 20 parts by weight of a C2-C12 alkyl (meth)acrylate monomer, based on 100 parts by weight of the total content of the monomer; at a point when a polymerization conversion ratio is 70% to 90% in the polymerization of the core, polymerizing the core by adding and polymerizing 1 part to 10 parts by weight of the methyl (meth)acrylate monomer and 0.04 to 0.7 parts by weight of a polyfunctional acrylic cross-linking agent; and polymerizing a core-shell copolymer by adding and polymerizing 1 to 10 parts by weight of the methyl (meth)acrylate monomer and 1 to 10 parts by weight of an aromatic vinyl monomer in the presence of the core.
