Polychloroprene latex, polychloroprene latex composition and dip molding product

摘要

PROBLEM TO BE SOLVED: To provide a polychloroprene latex having low modulus and excellent mechanical characteristics, and to provide a polychloroprene latex composition, and a dip molded product using the same.SOLUTION: There is provided a polychloroprene latex which includes 100 pts.mass of a modified polychloroprene obtained by copolymerizing chloroprene with methacrylic acid, 90-150 pts.mass of water, 1-5 pts.mass of an emulsifier, and 0.5-2.5 pts.mass of a potassium ion and has a pH of 7-14. It is preferable that the modified polychloroprene comprise 97-99 mass% of chloroprene and 1-3 mass% of methacrylic acid and that the emulsifier be a sulfonic acid group-containing alkali metal salt. A polychloroprene latex composition includes 1-10 pts.mass of a metal oxide and 0.1-3 pts.mass of sulfur based on 100 pts.mass of the modified polychloroprene in the polychloroprene latex.
