ABSTRACT:
Vinyl aromatic polymers having a minimum molecular weight of about 500,000, and preferably of about 1,500,000, are blended at levels of from about 1 to about 25% with thermoplastic resins to improve the melt rheology of the thermoplastic resins and facilitate blow molding, thermoforming, extrusion and similar processes.
