摘要
用小角Ｘ射线散射研究了嵌段聚氨酯阴离子离聚物中不同离子化程度对离子聚集体形态结构的影响．结果表明：离子含量少时，主要以非聚集离子或多重离子对的形式存在；离子含量多时，主要以离子簇的形式存在．聚氨酯离子化后，有利于软、硬段的微相分离．
he influences of different level of ionization on the morphology of the ionic aggregates in the block polyurethane anionomer were studedby the small angle X-ray scattering in this paper. The results indicated that it would mainly exist in the form of nonclustered ions or multiplets at lesser ion contents while in the form of clusters at higher ion contents. The ionization of the polyurethane is in favor of the microphase separation of the soft and hard segments.
