- (c2) polyamides;
- (c3) polyarylates;
- (c4) polyphenylene ethers;
- (c5) polysulfones; and
- (c6) acrylics selected from imidized acrylics or polymethyl methacrylate,
- wherein the above given weight percents are based upon the total weight of components (a), (b), and (c) only.
- 2. A polyoxymethylene blend consisting essentially of
- (a) 40 to 70 weight percent of an oxymethylene polymer,
- (b) 10 to 20 weight percent of a thermoplastic polyurethane, and
- (c) 20 to 40 weight percent of a polycarbonate,
- wherein said weight percents are based upon the total weight of components (a), (b), and (c) only.

- 11. The blend of claim 1 wherein the amorphous thermoplastic polymer is a styrene maleic anhydride copolymer.
- 12. The blend of claim 1 wherein the amorphous thermoplastic polymer is a polysulfone.
- 13. The blend of claim 1 wherein the amorphous thermoplastic polymer component is a blend of two or more amorphous thermoplastic polymers.
- 14. The blend of claim 1 wherein the polyoxymethylene polymer is a homopolymer.
- 15. The blend of claim 1 wherein the polyoxymethylene polymer is a copolymer.
- 16. The blend of claim 1 further comprising at least one of stabilizers, co-stabilizers, antioxidants, pigments, colorants, UV stabilizers, toughening agents, nucleating agents, and fillers.
- 17. Shaped articles made from the composition of claim 1.
- 18. A shaped article of claim 17 selected from the group consisting of sheet, profiles, rod stock, film, filaments, fibers, strapping, tape, tubing, and pipe.
