TITLE PROCESS FOR CROSSLINKING CHLOROSULFONATED OLEFIN POLYMERS ABSTRACT OF THE DISCLOSURE A process for crosslinking a chlorosulfonated olefin polymer which comprises contacting: a) a chlorosulfonated olefin polymer having a chlorine content of about 20-60% by weight and a sulfur content of about 0.5-10% by weight: with b) a compound selected from the group consisting of polyols, polyamines, and mixtures thereof, wherein the equivalent ratio of the compound to sulfur present in the chlorosulfonated olefin polymer is from 0.1:1 to 1:1 and the compound has an equivalent weight up to 1,000; with the proviso that when b) is a polyol alone, 0.1-2 equivalents, per equivalent of sulfur present in the chlorosulfonated olefin polymer, of a tertiary amine is additionally present; is disclosed as well as a process for making the same.
