ABSTRACT:
An improved molding composition is provided comprised of an oxymethylene polymer, a blocked or unblocked isocyanate compound in an amount ranging from about 0.2 to 2.0 percent by weight based on the weight of the polymer, a filler and an isocyanate-active catalyst. Shaped articles can be produced from the composition which exhibit desirable mechanical properties without the need for fibrous reinforcing agents.
