Abstract:
1. A polyoxymethylene molding composition comprising (A) from 0.1 to 5.0% by weight of a compatibilizer containing underlying units of the following formula: where R and R 2 are a hydrogen atom or an alkyl group having 1 or 2 carbon atoms, and where X is CH 3 or and at least one X is and where a is a number from 1 to 10, b is 0 or 1, c is a number from 0 to 10, l is a number from 0 to 10, R 3 and R 5 are hydrogen atom or a methyl group, R 4 is a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, m is 1 or 2, n is 0 or 1 or 2, x is an integer from 0 to 10, Y is H or where R 6 and R 7 are identical or different and are an alkyl group having from 1 to 4 carbon atoms, R 8 is an alkyl group having from 1 to 12 carbon atoms, phenyl, alkylphenyl or cycloalkyl having from 3 to 12 carbon atoms where the underlying units of the formula (Ia), (IIa), (IIIa), (IVa) and (Va) may have bonding to underlying units of the formula (I), (II), (III), (IV), or (V), and the compatibilizer comprises from 29 to 70% by weight of underlying unit of the formula (I) from 0.5 to 30% by weight of underlying unit of the formula (II) from 10 to 70% by weight of underlying unit of formula (III) and from up to 10% by weight of underlying units of the formula (IV) and/or (V), (B) from 5 to 50% by weight of an impact modifier, (C) from 0 to 40% of conventional additives selected from the group consisting of carbon blacks, acid scavengers, antioxidants, stabilizers, UV stabilizers, coupling agents, mold-release aids, substances to improve electrical conductivity, antistats, nucleating agents, colorants, fillers, lubricants, waxes, oils, and combinations thereof, (D) the remainder to 100% by weight of a polyoxymethylene.
