Abstract
The present invention relates to a method of preparing a graft copolymer powder, which includes: preparing a seed by adding one or more selected from the group consisting of an alkyl (meth)acrylate-based monomer, an aromatic vinyl-based monomer and a vinyl cyan-based monomer to a reactor and carrying out polymerization; preparing a core in the presence of the seed by adding an alkyl (meth)acrylate-based monomer and carrying out polymerization; and preparing a graft copolymer latex in the presence of the core by adding an aromatic vinyl-based monomer and a vinyl cyan-based monomer and carrying out polymerization; adding an alkyl methacrylate-based polymer to the graft copolymer latex and carrying out coagulation, and more particularly, to a method of preparing a graft copolymer powder that is excellent in weather resistance, fluidity, mechanical properties, surface gloss and appearance quality.
