Publication number: 20250002720Abstract: A polymeric composition includes 93 wt. % to 99 wt. % of a mixture containing a polyether block amide and a thermoplastic polyurethane; and 1 wt. % to 7 wt. % of a compatibilizer. The compatibilizer contains at least one or more modified siloxanes and/or one or more condensation products of at least one amino-functional polymer and at least one polyester. A method prepares the polymeric composition by compounding the polyether block amide, the thermoplastic polyurethane, and the compatibilizer to form a blend, and homogenizing the blend under rotation.
