Method for producing chlorosulfonated polyethylene with controlling addition amount of sulfur of the chlorosulfonated polyethylene

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: ##EQU1## wherein S: reaction yield (%) of sulfur of sulfuryl chlorideP PA: concentration (mol/liter) of amine compound in halogenated hydrocarbon solventP P&agr;,&bgr;: constants such that PP1.0 . alpha. 3.0PP4.0 &agr; 12.0.
