Abstract:
1. A thermoplastic polymer fiber comprising a blend of a polyolefin resin and a grafted polyolefin resin, the grafted polyolefin resin comprising an unmodified cyclodextrin grafted to an acid anhydride functionalized polyolefin resin, the acid anhydride functionalized polyolefin comprising acid anhydride functionality of about 0.02 to 5 weight % of the functionalized polyolefin, the fiber comprising the ungrafted polyolefin resin and a lesser amount of the grafted polyolefin resin; wherein the unmodified cyclodextrin is substantially free of a compound in the central pore of the cyclodextrin ring.
