    摘要: An excellent cold-proof chlorosulfonated polyethylene and a method of manufacturing the same featured in that a polyethylene is once dissolved in a solvent by heating up them over a dissolution temperature of the polyethylene, then cooled and thus obtained homogeneous solution of the polyethylene is allowed to react with a sulfuryl chloride in the presence of a catalyst of a radical generating agent in the dissolution temperature region of the polyethylene or in a temperature region lower than the former one.

    摘要: A method for producing chlorosulfonated polyethylene with controlled addition of the amount of sulfur added to the polyethylene. Polyethylene dissolved in halogenated hydrocarbon is reacted with sulfuryl chloride in the presence of a catalyst of a radical generating agent in a binary phase system. The addition amount of sulfur is controlled by adding an amine compound to the reaction in an amount within the range where the following formula is applicable:log.sub.10 S=.alpha..multidot.log.sub.10 A+.beta. (1)whereinS: reaction yield (%) of sulfur of sulfuryl chlorideA: concentration (mol/liter) of amine compound in halogenated hydrocarbon solvent.alpha.,.beta.: constants such that1.0
