Process for producing graft copolymer latex

摘要

There is provided a process for producing a copolymer latex obtained by graft-polymerizing a rubber latex and a graft-polymerizable monomer without decreasing productivity. In case of removing non-reacted monomer from a rubber latex before graft polymerization, non-reacted monomer is removed in a short time by adding an electrolyte to control foaming of a rubber latex, and a graft copolymer latex is prepared without decreasing productivity.
