| Abstract: | In this paper, by means of depolarized light intensity method, differential scanning calorimetry and polarizing optical microscope were used to investigation. It indicated that a maleic anhydride grafted polypropylene (mPP) is very effective to modify relationship of between the PP phase and the TLCP phase. The rate of crystallization and the crystallization point were enhanced in the PP/mPP/TLCP blends which exhibit PP transcrystallization at the surface of TLCP fibrils in PP melt. The crystallinity of the PP/mPP/TLCP blends were lower then the PP/TLCP blends. |
