Patent ID: 7915350

Claim:
A composition comprising a mixture of: i) a) a first polyoxymethylene homo- or copolymer, the first polyoxymethylene homo- or copolymer consisting essentially of at least 50 mol % of —CH 2 —O— repeat units, up to 50 mol % of —O—R 1 - repeat units, where R 1 is a saturated or ethylenically unsaturated alkylene group having at least two carbon atoms, or a cycloalkylene group, optionally, the residual of a monomer of the formula where Z is a chemical bond, —O—, or O—R 6 —O(R 6 =C 2 -C 8 -alkylene or C 2 -C 8 -cycloalkylene), and optionally, the first polyoxymethylene homo- or copolymer is an end-group-stabilized polyoxymethylene, and ii) a reaction product comprising: b) a thermoplastic elastomer having active hydrogen atoms, wherein the thermoplastic elastomer is selected from the group consisting of thermoplastic polyester elastomers (TPE-E), thermoplastic polyamide elastomers (TPE-A), thermoplastic polyurethane elastomers (TPE-U), and combinations thereof and c) a second polyoxymethylene which differs from component a) and contains active hydrogen atoms, wherein the thermoplastic elastomer and the second polyoxymethylene are covalently coupled by a coupling reagent d), wherein component d) comprises one or more compounds selected from the group consisting of diisocyanates, activated diesters, activated diamides, carbonyl biscaprolactamate, and mixtures thereof, and iii) e) optionally an impact modifier, which differs from component b); wherein component b), component c), component d) and optionally component e) are dispersed in component a).
