Abstract

PURPOSE: Titled composition which provides masses which are tough in the vulcanized or unvulcanized state and is useful as an adhesive etc., prepared by adding a hydrogen chloride-capturing agent or a vulcanization accelerator to a block copolymer comprising chain block structures of 2,3-dichlorobutadiene-1,3.
CONSTITUTION: A composition containing a hydrogen chloride-capturing agent and/or a vulcanization accelerator and a 2,3-dichlorobutadiene-1,3/chloroprene block copolymer having chain block structures of 2,3-dichlorobutadiene-1,3 and satisfying the following requirements (A), (B) and (C):(A) a m.p. of 80W130°C, when measured on a differential scanning colorimeter, (B) a number-average MW of 1× 104W50×104 and (C) a weight ratio between the copolymer-constituting monomer units, i.e., 2,3-dichlorobutadiene-1,3 and chloroprene, of 60/40W90/10. As the hydrogen chloride-capturing agents, there can be mentioned zinc white, calcium stearate and epoxidized soybean oil.
