Abstract

Molding compositions comprising a "terminally unsaturated"polyurethane, a copolymerizable vinyl or vinylidene compound and a rubbery-elastic polymer having a glass transition temperature of between -90.degree. and +10.degree. C. can be used for the preparation of molded articles having a considerably increased impact strength and a good heat distortion temperature, strength and rigidity.
