  • Patent number: 6872775
    Abstract: A compound for a composite body having a hard and a soft component, and to a process for producing such a composite body is provided. The compound comprises a hard component (a) of a polyoxymethylene and a soft component (b) of one or more hydrogenated styrene block copolymers, molded directly onto component (a). The styrene block copolymers are from the group of poly-isoprene/butadiene polymer (SEEPS), poly-isoprene polymer (SEPS); poly-butadiene polymer (SEBS), and combinations thereof. The styrene block copolymer is adhesion-modified by the addition of a compound selected from styrene/butadiene copolymer (SBS); ethylene/vinyl acetate copolymer (EVA); olefinic polymers, polystyrene (PS), and combinations thereof.
