Abstract:
A polymer blend composition comprising:a) from about 10 to about 95 wt. % of said polymer blend composition being at least one halogen-free hydrogen-bond acceptor polymer resin selected from the group consisting of polyurethanes, polycarbonates, polyesters, polyamides. copolyesters, copolyamides and mixtures thereof; b) from about 0.01 to about 10 wt. % of said polymer blend composition being at least one block chlorinated polyolefin having at least above 25 wt. % residual blocks of crystalline polyolefin based on 100% of the weight of crystalline blocks of the polyolefin precursor, wherein said block chlorinated polyolefin has both crystalline and amorphous realons in its backbone; and c) from about 5 to about 90 wt. % of said polymer blend composition being at least one blend partner selected from the group consisting of methylmethacrylate-butadiene-styrene copolymers, acrylonitrile-butadiene-styrene copolymers, styrene acrylonitrile copolymers, styrene-butadiene-styrene copolymers, styrene-ethylene-butylene-styrene copolymers, styrene-isoprene-styrene copolymers, polypropylene, polyethylene, polypropylene copolymers, polyethylene copolymers, and mixtures thereof.
