AbstractMaleic anhydride-grafted polysulfone (PSF-g-MAH) was prepared. Compared to polysulfone I the surface tension and its polar fraction of PSF-g-MAH were increased by modification. The PSF-g-MAH was used to compatibilize polysulfone (PSF)/liquid crystalline polymer(LCP) blends. The process-abilities and the interfacial properties of PSF/LCP blends before and after compatilization were investigated. It was found that the melt viscosities were increased by the addition of PSF-g-MAH. DRS-FTIR investigations showed that the special interaction between PSF and LCP phases was increased due to the incorporation of PSF-g-MAH. The XPS and PLM studies revealed that some chemical reactions had occurred between mPSF and LCP phases, which produced PSF-VB copolymers. It is suggested that the compatibility is attributed to some interactions including both chemical and physical ones. A model to illustrate the compatibilization of mPSF in PSF/VB blends has been proposed.
