THERMALLY PROCESSABLE BLENDS OF HIGH MODULUS POLYURETHANES AND IMPACT MODIFIERS |
| 摘要 |
The toughness of a thermoplastic, rigid polyurethane is markedly improved by incorporating an NCO-reactive impact modifier such as styrene/butadiene rubber grafted with a copolymer of styrene, acrylonitrile and 2-hydroxyethyl acrylate. This toughened polyurethane is particularly useful in making structural automotive body parts and housings for electrical appliances. |
