Document Type and Number:

WIPO Patent Application WO/2019/151776

Kind Code:

A1

Abstract:

The present invention relates to a preparation method of a graft copolymer, a graft copolymer, and a thermoplastic resin molded article. The preparation method comprises a step of polymerizing a first conjugated diene-based polymer, a second conjugated diene-based polymer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer, wherein the first conjugated diene-based polymer has a particle size distribution between 0.346 and 0.404, and the second conjugated diene-based polymer has a particle size distribution between 0.196 and 0.304.
