Abstract

Moulding compounds consisting of a mixture of (A) from 99.99 to 60 parts, by weight, of a polyoxymethylene; (B) from 0 to 40 parts, by weight, of an elastomer having a softening temperature below the crystallite melting point of polyoxymethylene (A) and a freezing point below 0.degree. C.; and (C) from 0.01 to 40 parts, by weight, of an aliphatic, rubber-like, high molecular weight adipate-carbonate mixed ester.
