Impact-resistant polyoxymethylene molding materials

A thermoplastic molding material containing

• A) from 10 to 97% by weight of a polyoxymethylene homo- or copolymer,
• B) from 3 to 50% by weight of a thermoplastic elastomer selected from the group consisting of the thermoplastic polyurethanes, the polyetheresters and the polyetheramides, the flexible phase of which is derived from polyetherpolycarbonatediols,
• C) from 0 to 50% by weight of a fibrous or particulate filler or a mixture thereof and
• D) from 0 to 30% by weight of processing assistants,
• wherein the polyetherpolycarbonatediols which form the flexible phase of the thermoplastic elastomer B) are essentially composed of:
• b.sub.1) from 3 to 63.7 mol % of units which are derived from a polyoxytetramethylenediol,
• b.sub.2) from 63.7 to 3 mol % of units which are derived from a polyoxyalkylenediol differing from b.sub.1) and having C.sub.2 -C.sub.8 -alkylene groups, an aliphatic alkanediol of 2 to 14 carbon atoms, an alicyclic alkanediol of 3 to 14 carbon atoms or an alkylene oxide of 2 or 3 carbon atoms or a mixture thereof, and
• b.sub.3) from 33.3 to 50 mol % of units which are derived from phosgene, a dialkyl carbonate having C.sub.1 -C.sub.4 -alkyl groups or a cyclic carbonate having C.sub.2 -C.sub.4 -alkylene bridges or a mixture thereof.
