ABSTRACT:
N-halothiosulfonamide-modified non-rubbery thermoplastic polyolefins are provided. The modified polyolefin products are prepared by reaction of a non-rubbery thermoplastic polyolefin polymer with an N-halothiosulfonamide in the absence or, preferably, in the presence of a catalyst. The preferred catalyst for use in the preparation of these products are salts of weak acids of specified metals.
