摘要: 聚合物共混物共混过程结构发展的研究较多[1~3],一致结论是分散相尺寸的迅速降低主 要发生在最初1.5min到2min.当材料处于熔融或软化过程时,结构将发生极大的变化.材料在共混中往往出现薄片状或带状结构,基本处于微米尺度.本文利用X光小角散射、激光背 散射及扫描电镜分别从微米尺度和纳米尺度对共混过程中微观结构的动态变迁进行了讨论.

Abstract: The correlation distance ac and integration invariant Q of the blends of polystyrenewith cis-polybutadiene-g-styrene in melt-mixing have been assessed through small angle lightscattering and small angle X-ray scattering investigations.The changes of the phase struc-ture of the blends with blending time have been examined by SEM.

Key words: polymer blend, light scattering, phase structure
