Abstract
Mechanical properties, especially tensile and impact properties, of molding compositions comprising at least one thermoplastic oxymethylene polymer and optionally also containing an impact-enhancing amount of a polyurethane, can be improved by incorporating into the molding composition an effective amount greater than 10 weight percent of the composition of a monomeric formaldehyde/amino compound condensation product or prepolymeric amino resin selected from condensation products of formaldehyde and at least one of guanidine, urea, a substituted or unsubstituted guanamine and melamine, preferably having a degree of polymerization of about 2-5. An acid catalyst can be employed to promote the cross-linking reactions of the prepolymeric amino resin. In the compositions comprising polyurethane, amounts of the amino resin of less than 10 weight percent can be used.
