Abstract
The toughness of a thermoplastic, rigid polyurethane is markedly improved by incorporating a mass ABS resin such as styrene/butadiene rubber grafted with a copolymer of styrene and acrylonitrile. This toughened polyurethane is particularly useful in making structural automotive body parts and housings for electrical appliances.
