摘要： 互穿网络高聚物(IPN)是两种或多种交联聚合物的共混体。由于两种聚合物网络相互贯穿和缠结,链节间的永久锁结产生强迫互容,使不同聚合物达到最紧密混合,最大限度地控制多相体系的相分离[1],IPN材料显示不寻常的耐热,耐溶剂和高强度等特点,远远超过其聚合物本身的性能[2,3]。在IPN中,两网络相互贯穿程度越高,相分离越低,这主要取决于构成聚合物本身的相容性和最终网络结合方式[4]。

Abstract: In this paper, the synthesis of interpenetrating polymer nelworks(IPN) based on polyurethane and epoxide by simultaneous polymerization, the influence of various component on their morphology, gh-ss transition behavior,mechanical properties and thermostability are reported. The results show that PU/EP = 25/75 exhibited the best, mechanical properties and thermostability due to the high degree of interpenetration among the networks. PU/Ep = 50/50 exhibited obvious phase separation and the poorest mechnical properties.

Key words: PU/EP, Interpenetrating
