TITLE CHLOROSULFONATED POLYOLEFIN-MODIFIED POLYURETHANE AND POLYUREA COMPOSITIONS AND PROCESS FOR MAKING SAME A chlorosulfonated olefin polymer resin composition comprising the reaction product of: a) 1-80% by weight, based on the weight of the resin, of 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; b) 5-90% by weight, based on the weight of the resin, of a compound selected from the group consisting of polyols, polyamines, and mixtures thereof, wherein the equivalent ratio of the compound to sulfur in the chlorosulfonated olefin polymer is greater than 1:1 and the compound has an equivalent weight up to 5,000; and c) at least 5% by weight, based on the weight of the resin, of a polyisocyanate; is disclosed as well as the process for making same.
