Title:
クロロプレングラフト共重合体ラテックスの製造方法
Document Type and Number:
Japanese Patent JP7037862
Kind Code:
B2
Abstract:
Provided is a method for producing a chloroprene graft copolymer latex containing no organic solvent and exhibiting high adhesive strength even for soft polyvinyl chloride. A method for producing a chloroprene graft copolymer latex includes a chloroprene polymerization step of giving a chloroprene polymer latex and a graft copolymerization step of giving a chloroprene graft copolymer latex. The chloroprene polymerization step is a step of subjecting at least chloroprene (A-1) of chloroprene (A-1) and a monomer (A-2) copolymerizable with chloroprene (A-1) to emulsion radical polymerization. The graft copolymerization step is a step of adding, to the chloroprene polymer latex, a (meth)acrylate (B) and an organic peroxide (C) having an octanol/water partition coefficient of −2.0 or more and 3.0 or less to subject the chloroprene polymer to graft copolymerization with the (meth)acrylate (B) at a temperature of 10° C. or more and 40° C. or less.
