Abstract
Provided is a polychloroprene latex that shows favorable low-temperature stability without deterioration in the rubber agglutinating property during production of the dip-molded article, a rubber composition, and a dip-molded article, prepared by using the same. Prepared is a polychloroprene latex of a chloroprene copolymer obtained by polymerization of raw monomers at least containing chloroprene and 2,3-dichloro-1,3-butadiene, which is dispersed in water, wherein the 2,3-dichloro-1,3-butadiene content in the raw monomers is controlled to 1 to 30 mass % and the potassium ion content is adjusted to 0.7 to 1.5 parts by mass and the sodium ion content to 0.2 part or less by mass with respect to 100 parts by mass of the solid matter. In addition, a metal oxide: 1 to 10 parts by mass, sulfur: 0.1 to 3 parts by mass, an aging inhibitor: 0.1 to 5 parts by mass and a surfactant: 0.1 to 10 parts by mass, respectively with respect to 100 parts by mass of the solid matter, were added to the chloroprene latex, to give a rubber composition.
