Abstract

This invention relates to thermoplastic moulding compositions of PVC and poly-.alpha.-olefine/polyurethane block copolymers and poly-(C.sub.2 -C.sub.10 -.alpha.-olefines) which have been functionalized in relation to isocyanate groups, preferably polypropylene, di- or higher poly-isocyanates or isocyanate prepolymers and optionally relatively high molecular weight polyols and/or low molecular weight chain lengthening agents.
