POLYOXYMETHYLENE COMPOSITION |
摘要 |
A polyoxymethylene composition which is improved in thermal stability, little stains the mold even in continuous long-term molding work, and is extremely reduced in the emission of a formaldehyde smell. The composition comprises polyoxymethylene, 0.01-5 wt. % of an antioxidant and 0.01-10 wt.% of a melamine-formaldehyde polycondensate, each based on the polyoxymethylene. The polycondensate to be used is one which is prepared by the reaction of mainly melamine and formaldehyde and contains on average 2.0-10 mol of melamine units per mole, and wherein 3 mol of the amino groups contained in 1 mol of melamine have on average at least 3.0 mol of hydrogen. |
