Abstract
Polyoxymethylene compositions are stabilized by a blend of thermoplastic polyurethane with polyamide where the polyamide is dispersed throughout the polyurethane as a separate phase having substantially all of the polyamide particles with a diameter of less then six microns and where the polyamide comprises 0.2 to 5 weight percent based on the quantity of polyoxymethylene.
