Abstract
Self-stabilized resin latexes are provided which contain sulfonate salts produced by basic hydrolysis of chlorosulfonated C.sub.2 -C.sub.8 alpha-olefin polymers having chlorine contents of 20-70 weight percent and sulfur contents of 1.5-10 weight percent. Further provided is a novel composition comprising a chlorosulfonated graft-modified ethylene/propylene copolymer.
Claims6
A self-stabilized chlorosulfonated resin latex composition comprising an aqueous emulsion of a salt of a chlorosulfonated C.sub.2 -C.sub.8 alpha-olefin homopolymer, said chlorosulfonated homopolymer having a chlorine content of 20-70 weight percent and a sulfur content of 1.5-10 weight percent with the proviso that the latex is substantially free of surfactants.
A self-stabilized chlorosulfonated resin latex composition comprising an aqueous emulsion of a salt of a chlorosulfonated copolymer of a C.sub.2 -C.sub.8 alpha-olefin and at least one other ethylenically unsaturated monomer selected from the group consisting of C.sub.3 -C.sub.10 alpha monoolefins and carbon monoxide, said chlorosulfonated copolymer having a chlorine content of 20-70 weight percent and a sulfur content of 1.5-10 weight percent, with the proviso that the latex is substantially free of surfactants.
