Patent ID: 8148466

Claim:
A thermoplastic polymer composition, the composition capable of formation into thermoplastic fiber, film, fabric or web, consisting essentially of: (a) a blend of a polyolefin resin and an anhydride-modified polyolefin resin, (b) a stoichiometric reaction product of a cyclodextrin and the anhydride-modified polyolefin resin, and (c) an alkaline earth metal on the anhydride-modified polyolefin resin; wherein the polymer composition has a tri-functional trapping mechanism, the trapping mechanism consisting of carboxylic acid groups corresponding to the anhydride, the anhydride half-ester product of cyclodextrin, and a metal or organic group bonded to some portion of the anhydride half-acid groups; wherein the cyclodextrin is substantially free of an inclusion complex including residual polymer contaminant.
