Abstract:
1. A sulfur-modified chloroprene rubber comprising, as the principal component, a sulfur-modified chloroprene polymer having sulfur atoms in the molecule which is obtained by emulsion polymerization of chloroprene alone or a mixture of chloroprene and one or more other monomers in the presence of sulfur, and wherein tetraethylthiuram disulfide has been used as a plasticizer, wherein: the content of the sulfur that is bound to the sulfur-modified chloroprene polymer is 0.2 to 0.6 mass % with respect to the total amount of the rubber; and the ratio of the amount of the bound sulfur (mass %) to the total amount of the sulfur contained in the entire rubber (mass %) (bound sulfur content/total sulfur content) is 0.3 to 0.45.
