Abstract
Provided are a polychloroprene latex composition giving immersion-molded articles superior in releasability from the mold during immersion molding and also superior in flexibility, a production method thereof and a molded article prepared by using the same.A polychloroprene latex composition containing an alkyldiphenyletherdisulfonic acid alkali-metal salt in an amount of 0.01 to 1.0 part by mass with respect to 100 parts by mass of a polychloroprene latex is prepared by emulsion polymerization of the monomer in the presence of a rosin acid alkali-metal salt and an alkyldiphenyletherdisulfonic acid alkali-metal salt each in an amount of 3 parts or less by mass with respect to 100 parts by mass of the monomer.
