Zusammenfassung:	The invention relates to mixture composed essen- tially of polyoxymethylene and of 5 to 60% by weight of a polyurethane, the polyurethane being built up exclus- ively from aliphatic components and having an elongation at break of 800 - 1,500% and a Shore hardness A not ex- ceeding 81. The shaped articles produced from the mixture according to the invention are distinguished, above all, by an improved notched impact strength and by matt sur- faces.
