Abstract

NEW MATERIAL: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 calorimeter, (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 60/40-90/10.
USE: Hot melt adhesive, lining material, coating material, sealant and heat-shrinking film (even in the unvulcanized state shows excellent mechanical properties) In the presence of a vulcanization accelerator, the composition can be vulcanized into a vulcanizate having better mechanical properties and solvent resistance than in the unvulcanized state.
PREPARATION: 2,3-Dichlorobutadiene is copolymerized, by bulk, solution or emulsion polymerization, with 1,3-chloroprene.
