Claim:
1. A thermoplastic polyurethane composition comprising the product of a reaction mixture comprising (i) a polyisocyanate component, (ii) at least one of a chain extender component or a polyol component, and (iii) a chain terminator component; wherein the chain terminator component comprises a short chain crystalline compound containing 26 to 70 carbon atoms and a single NCO-reactive functional group capable of terminating a chain of a thermoplastic polyurethane resulting from the reaction of components (i) and (ii), wherein the short chain crystalline compound comprises one or more alpha-hydroxy terminated polyalphaolefins selected from a polyethylene, a polypropylene, a poly(ethylene-co-alphaolefin) copolymer, a poly(propylene-co-alphaolefin) copolymer, or any combination thereof; and wherein the thermoplastic polyurethane composition comprises a crystalline end group formed by the chain terminator component.
