Abstract

Thermoplastic molding compositions of polyoxymethylenes and glass fibers and containing from 0.1 to 5.0 per cent, by weight of the total weight of the mixture, of alkoxymethyl ureas having the formula ##EQU1## where R.sup.1 and R.sup.2 are the same or different and denote straight-chain or branched-chain alkyl of from 1 to 10 carbon atoms and R.sup.3 and R.sup.4 denote hydrogen or alkyl, or R.sup.3 and R.sup.4 are joined together to form a heterocyclic ring with the adjacent ureido group.
