Title:
GRAFT COPOLYMER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/101275
Kind Code:
A1
Abstract:
The present invention relates to a graft copolymer production method comprising the steps of: preparing a liquid-phase maleimide-based monomer; preparing a reaction solution comprising a dienic rubber polymer, an aromatic vinyl-based monomer and a vinyl cyanide-based monomer; and polymerizing the liquid-phase maleimide-based monomer and the reaction solution by inputting same in a reactor. According to the production method of the present invention, the polymerization participation rate of the maleimide-based monomer may be increased, and the color properties, glass transition temperature and softening temperature of the graft copolymer may be improved.
