ABSTRACT:
A compatibilized thermoplastic molding composition containing polyurethane and polyolefin resins is disclosed. Accordingly, a particularly structured copolymer having a number average molecular weight of about 25,000 to 350,000 and containing blocks of monoalkylene arene and either hydrogenated conjugated diene or non-hydrogenated conjugated diene, was found to compatibilize the composition. Articles molded from the composition are characterized by their good mechanical properties.
