Abstract
Blends are disclosed of a clear polyurethane plastic and a minor amount (up to 30 parts by weight per 100 parts by weight of blend) of an incompatible polymeric impact modifier. The resulting blends exhibit properties (high impact resistance, high flexural modulus and resistance to heat) comparable to those of engineering plastics such as nylon.
