ABSTRACT:
Incorporation of a thermoplastic polyurethane and at least one thermoplastic crystalline polymer selected from nylon 6, nylon 612, polypropylene, and polyalkylene terephthalates containing at least one ethylene copolymer into polyacetal polymer results in blends characterized as having improved toughness, or impact strength, and improved elongation over that of a comparable blend of polyacetal and at least one of said crystalline polymers alone.
