共聚物增容剂可以提高不相容高分子共混物两相的相容性,从而强化共混物的宏观机械性能。增容剂通过对共混物界面性质的改善,对共混物的相形态和粘弹性都有很大的影响。目前对增容作用的研究已不再局限于对其增容原理的探索及增容效果的评价,还集中于揭示增容剂对高分子共混物在流场下的形态演变与流变行为的影响。本文从上述方面对近期的研究进展进行了总结,并归纳了增容剂的分子结构、加工条件等因素对流场下增容体系微观结构形成的影响。
Copolymer compatibilizer can improve the incompatibility of two phases of incompatible polymer blends to enhance the macroscopic mechanical properties of blends. The compatibilizer has a great influence on the phase morphology and viscoelasticity of blends by improving the interfacial properties of blends. At present, the research on the compatibilization is no longer limited to the exploration of its principle of compatibilization and the evaluation of its compatibilization effect, but also focuses on revealing the morphological evolution and rheological behavior of the polymer blends under the flow field Impact. This article summarizes the recent progress in the above aspects and summarizes the influence of the compatibilizer molecular structure, processing conditions and other factors on the microstructure of the compatibilization system under flow field.
