Self-reinforcing polyurethane compositions. |
摘要 |
<p>A polyurethane liquid crystal polymer-reinforced RIM composition having superior impact strength and flexural modulus is produced by a reaction-injection-moulding process. The chemistry involved in the preparation of this reinforced RIM material includes the simultaneous reaction and formation of a polyurethane liquid crystal polymer and a polyurethane RIM.</p> |
