The invention provides a composition comprising the following: at least one olefin-based polymer, at least one halogenated ethylene-based polymer, or at least one elastomer rubber; at least one thermoplastic polyurethane; and at least one polydiene- or polydiol-based polyurethane. These compositions
The invention provides a composition comprising the following: at least one olefin-based polymer, at least one halogenated ethylene-based polymer, or at least one elastomer rubber; at least one thermoplastic polyurethane; and at least one polydiene- or polydiol-based polyurethane. These compositions are well-suited for promoting the adhesion between polar (for example, polyester, polycarbonate and polylactic acid) and non-polar materials and for the manufacture of, among other things, films, fibers, sheets and tie layers, tubes, adhesives, dispersions, protective apparel, footwear, coatings, laminates and foams.

A dispersion comprising the composition of claim 1. 13. The dispersion of claim 12, wherein the dispersion further comprises at least one additive of selected from the group consisting of an acrylic polymer, an alkyd resin, a cellulose-based material, a melamine resin, a urethane resin, a carbamate resin, a polyester resin, a vinyl acetate resin, an epoxy a polyol, an alcohol, and combinations thereof. 14. An injection molded article comprising at least one component formed from the composition of claim 1. 15. A molded article comprising a first component and a second component, and wherein the first component is formed from a composition comprising a polar polymer, and wherein the second component is formed from the composition of claim 1. 16. A footwear article comprising at least one component formed from the composition of claim 1. 17. An automotive part comprising at least one layer formed from the composition of claim 1. 18.
