Abstract

Provided are: a polychloroprene latex in which rubber aggregability is improved and with which it is possible to obtain a film having excellent strength by dip-molding; a polychloroprene latex composition; and a molded article. This polychloroprene latex obtained by polymerizing 2-chloro- 1,3-butadiene alone or by polymerizing raw-material monomers including at least 2- chloro -1,3 -butadiene and 2,3-dichloro -1,3 -butadiene has a precipitation rate calculated according to mathematical formula (I) of 5- 40%. In mathematical formula (I): A is the mass (g) of a dried product of a precipitate obtained by adding, dropwise over a period of two minutes, 50 ml of a saturated aqueous solution at 23°C of calcium hydroxide to 50 g of a latex adjusted so as to have a solids concentration of 45-65 mass% and a liquid temperature of 23°C, filtering and collecting the produced precipitate with a 80-mesh metal screen, and drying the precipitate at 1 10°C for 3 hours; B is the mass (50 g) of the latex before the dropwise addition; and C is the solids concentration (mass%) of the latex before the dropwise addition.
