摘要
Mechanical properties, especially tensile and flexural properties and impact strength, of glass fiber reinforced oxymethylene polymer molding compositions can be enhanced by incorporating into the molding compositions an effective amount of a prepolymeric amino resin, whereby the glass fiber reinforcing agent and the oxymethylene polymer are coupled. The amino resin can be a condensation product of formaldehyde and melamine, urea, guanidine, guanamine or a substituted guanamine. An acid catalyst is preferably employed to promote the cross- linking of the prepolymeric amino resin.
