Patent ID: 8318866

Claim:
A molding material containing a) a polyoxymethylene homo- or copolymer having at least 70%, based on the total number of terminal groups, of terminal hydroxyalkylene groups, wherein the polyoxymethylene has been polymerized in the presence of a molecular weight regulator and wherein unstable chain ends of the polyoxymethylene have been degraded by hydrolysis, the polyoxymethylene having a melt volume rate MVR of less than 20 cm 3 /10 minutes, measured according to ISO 1133 at 190° C. and 2.16 kg, and wherein the proportion of component a) of low molecular weight polymers having molecular weights below 10 000 dalton is less than 15% by weight, based on the total mass of the polyoxymethylene, the polyoxymethylene being present in the molding material an amount of from 30% to 95% by weight; b) a thermoplastic elastomer that has active hydrogen atoms; and at least one component c) which contains groups for covalent coupling of the components a) and b).
