Chlorosulfonated polyolefin-modified polyurethane and polyurea compositions and process for making same

Abstract

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, hydrocarbon primary and secondary polyamines, condensation products of said polyamines with aliphatic, cycloaliphatic, or aromatic polycarboxylic acids, 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.
