Abstract
The invention provides a molding composition of a mixture of an oxymethylene polymer, an elastomer having a softening temperature of below the crystallite melting point of the oxymethylene polymer and a second order transition temperature of from -120.degree. to +30.degree. C., and a segmented thermoplastic copolyester. The molding composition of the invention is distinguished by improved mechanical properties, especially with respect to the impact strength.
