THERMOPLASTISCHES POLYETHERURETHAN |
摘要 |
<p>A thermoplastic polyether polyurethane having good rebound resilience and low hysteresis properties is prepared by the reaction of a diisocyanate with a hydroxyl terminated polyether having a weight average molecular weight of at least 1,400 and a glycol chain extender. The polyether contains alkylene oxide repeat units having from 2 to 6 carbon atoms and the chain extender glycol has from 2 to 16 carbon atoms. The amount of the chain extender glycol is from about 0.25 to about 2 moles per mole of the polyether.</p> |
