Abstract

Disclosed is a polychloroprene elastomer composition having an excellent balance between extrusion processability and mechanical properties. Specifically disclosed is a polychloroprene elastomer composition produced by mixing a polychloroprene sol (A) and a polychloroprene gel (B) at a mixing ratio ((A)/(B)) of 30/70 to 80/20 by mass in terms of solid polymer contents. The polychloroprene sol (A) is a polychloroprene sol produced by emulsion-polymerizing a mixture of monomers 2-chloro-1,3-butadiene and 2,3-dichloro-1,3-butadiene in the presence of a molecular weight-controlling agent. The polychloroprene gel (B) is a polychloroprene gel produced by emulsion-polymerizing 2-chloro-1,3-butadiene, 2,3-dichloro-1,3-butadiene and a polyfunctional monomer having two or more vinyl groups in its molecule in the presence of a molecular weight-controlling agent, wherein 2-chloro-1,3-butadiene and 2,3-dichloro-1,3-butadiene are added in divided portions.
