Abstract:
1. A process comprising: molding a polyoxymethylene composition, wherein the molded polyoxymethylene composition exhibits at least one of the properties selected from the group consisting of: (A) a melt viscosity stability, as measured by ASTM D3835 at 220° C. and 100 s (B) a decrease in relative apparent capillary melt viscosity, as measured by ASTM D-3835 at 220° C. and shear rate 55 sec (C) an increase in flow length, as tested under Flow Length Test Conditions, of at least 5 percent when compared to the flow length of a composition consisting of the same polyoxymethylene polymer and the same additives and fillers, measured under the same conditions; and (D) when molded into a Type I specimen, an increase in elongation at break, as measured according to ASTM D638-08 at a speed of testing of 50 mm per minute, of least 4 percent when compared to the elongation at break of a composition consisting of the same polyoxymethylene polymer and the same additives and fillers, measured under the same conditions.
