Abstract

The present disclosure relates to a polymer composition and a method for making the same. The polymer composition comprises 93% to 99% by weight of a mixture comprising a polyether block amide and a thermoplastic polyurethane; and 1% to 7% by weight of a compatibilizer, the compatibilizer comprising at least one of one or more modified siloxanes; or one or more condensation products of at least one amino-functional polymer and at least one polyester.
