ABSTRACT:
Thermoplastic synthetic polymeric compositions of certain polyurethanes, polyamides or chlorinated polyolefins, having processing temperatures in the range of about 150.degree. to 325.degree. F., can be modified by the addition of a millable thermoplastic polyurethane elastomer thereto to lower the processing temperature by 10.degree. to 30.degree. F. or more. This modification enables the thermoplastic composition to be processed on conventional calendering or extrusion equipment with a lesser amount of energy or with better performance. Also, coated fabrics of such thermoplastic compositions and a fiber reinforcement.
