摘要： A chloroprene rubber having a shade of white only slightly tinged with pale yellow and exhibiting good tackiness is prepared by an aqueous radical emulsion polymerization of chloroprene or a mixture comprised of chloroprene and a copolymerizable monomer, wherein the polymerization is effected by using an alkali metal salt of a disproportioned rosin acid as an emulsifier, and a water-soluble polymeric substance as a dispersion stabilizer which has a sulfonic acid group and/or sulfate ester groups, which group has been introduced by an addition polymerization procedure or by a procedure of a polymeric reaction following an addition polymerization.
