Claims
- 1. A composition consisting essentially of (A) 80-99 percent by weight of a polyacetal, (B) 0.5-10 percent by weight of at least one lubricant and (C) 0.5-10 percent by weight of an ethylene-based random polymer of the formula E/X/Y wherein
- E is ethylene,
- X is selected from the group consisting of methyl acrylate, butyl acrylate, and ethyl acrylate,
- Y is selected from the group consisting of glycidyl methacrylate, glycidyl acrylate, and glycidyl vinyl ether, and wherein E/X/Y comprises 60-98.5 percent by weight E, 0.5-35 percent by weight X and 1-10 percent by weight Y, as based upon the total weight of E, X, and Y only, and further provided that the weight percent of (A), (B), and (C) is based upon the total weight of (A), (B), and (C) only.
- 2. The composition of claim 1 wherein the component (A) polyacetal is a homopolymer.
- 3. The composition of claim 1 wherein the component (A) polyacetal is a copolymer.
- 4. The composition of claim 1 wherein the component (B) lubricant is selected from the group consisting of paraffin wax, polytetrafluoroethylene, fatty esters, fatty amides, silicone oil, polyethylene glycol, polytetramethylene glycol, and polypropylene glycol.
- 5. The composition of claim 1 wherein the component (B) lubricant is selected from paraffin wax, ethylene glycol distearate, ethylene bis(stearamide), polytetramethylene glycol, and polyethylene glycol.
- 6. The composition of claim 1 wherein the component (C) is an ethylene/butyl acrylate/glycidyl methacrylate random polymer.
- 7. The composition of claim 1 wherein the component (C) is an ethylene/glycidyl methacrylate random polymer.
- 8. The composition of claim 1 further containing at least one of thermal stabilizers, antioxidants, tougheners, colorants, UV stabilizers, nucleating agents, fillers, and reinforcing agents.
- 9. Shaped articles made from the composition of claim 1.
- 10. A shaped article of claim 9 selected from the group consisting of gears, cams, conveyor chains, sheet, profiles, rod stock, film, filaments, fibers, strapping, tape, tubing, and pipe.
