Abstract

A method for producing a polymer latex includes: a preparation step of reducing the weight average molecular weight of a conjugated diene polymer (A) by 20 to 70 mass %, thereby obtaining an organic solvent solution containing a conjugated diene polymer (B) having a weight average molecular weight lower than that of the conjugated diene polymer (A); and an emulsification step of emulsifying the organic solvent solution in water in the presence of a surfactant, thereby obtaining a polymer latex.
