METHOD FOR MANUFACTURING THERMOPLASTIC RESIN POWDER

摘要

The resin powder is prepared by the method of the 1, 2 stages emulsion polymerizing a rubber polymer, unsaturated nitrile monomer and vinyl aromatic compound monomer and after treatment process to give a thermoplastic resin. Especially, an ion exchange water is introduced before carrying out after-treatment process toward the thermoplastic resin latex obtained by 1,2 stages to coagulate it. The thermoplastic resin powder has a good appearance and shock resistance.
