Abstract

A thermoplastic, resinous mixture, useful in the preparation of compatible blends of polyurethane with polyolefins, is disclosed. The mixture contains PA1 (i) a thermoplastic polyurethane, and PA1 (ii) an agent which is the product of the reaction between a polyamide and a modified polyolefin. The inventive mixture may be used as a component in thermoplastic molding compositions which contain a polyolefin, preferably polypropylene. Improved mechanical properties characterize the molding compositions thus prepared.
