Abstract
A polychloroprene latex is provided with excellent adhesive strength, particularly for an EVA material, by dissolving an ethylene/vinyl acetate copolymer in a chloroprene monomer alone or in a mixture of a chloroprene monomer and a monomer copolymerizable with chloroprene to prepare a monomer solution, which is emulsified and dispersed in an aqueous solution containing an emulsifier and/or a dispersant, followed by polymerization to produce a polychloroprene latex. The obtained polychloroprene latex can provide improved adhesive strength particularly for an EVA material.
