摘要：
A technique for manufacturing a sulfur-modified chloroprene rubber wherein the sulfur-modified chloroprene rubber is excellent in the permanent compression set and abrasion resistance, and the heat build-up is reduced is provided. Provided is a sulfur-modified chloroprene rubber composition comprising, 0.0005 to 0.01 parts by mass of a sulfenamide optionally having a substituent in a sulfur-modified chloroprene rubber comprising at least a sulfur-modified chloroprene polymer and an emulsifier, based on 100 parts by mass of the sulfur-modified chloroprene rubber.
