Thermoplastic urethane elastomeric alloys are obtained by melt compounding at least one first component that is a polyurethane elastomer having at least one plasticizer reacted therein, this first component being formed by heating a reaction mixture comprising at least one isocyanate having a functionality of less than about 2,2, at least one long chain polyol, at least one chain extender and at least one plasticizer in specified amounts at a temperature of at least about 330 DEG F (165.6 DEG C), with at least one second component that is another thermoplastic elastomer not within the definition of the first component. |
