Abstract: 1. AN IMPROVED THERMOPLASTIC MOLDING COMPOSITION OF POLYOXYMETHYLENES SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS OF FORMALDEHYDE AND COPOLYMERS OF FORMALDEHYDE OR TRIOXANE, SAID HOMOPOLYMERS HAVING THERMALLY STABLE END GROUPS AND SAID COPOLYMERS CONTAINING MORE THAN ABOUT 50% OF OXYMETHYLENE GROUPS AND AT LEAST ABOUT 0.1% OF THE COMONOMER HAVING AT LEAST TWO VICINAL CARBON ATOMS, FROM 10 TO 60% BY WEIGHT OF GLASS FIBERS, AND FROM 0.5 TO 10% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF THE MIXTURE, OF A HIGH MOLECULAR WEIGHT POLYURETHANE EXHIBITING THERMOPLASTIC PROPERTIES, SAID POLYURETHANE HAVING BEEN PREPARED FROM POLYESTERS, POLYETHERS SUCH AS POLYETHYLENEGLYCOL ETHERS, POLYPROPYLENEGLYCOL ETHERS OR POLYACETALS HAVING FREE HYDROXYL END GROUPS AND POLYISOCYANATES USING CHAIN-EXTENDING AGENTS SUCH AS LOW MOLECULAR WEIGHT POLYOLS.

Abstract: Method of removing odorous formaldehyde from stabilized shaped polyoxymethylenes in which an inert gas is caused to flow over stabilized and shaped solid polyoxymethylenes at elevated temperatures not high enough to cause sticking or fusion of the polyoxymethylene, until substantially all of the volatile formaldehyde has been removed.
