| Abstract: | PP g AA(FPP) was prepared by melt extrusion. Physical properties of FPP and effect of FPP on mechanical properties of polypropylene(PP) have been investigated. The results indicate that crystallization peak temperature( T c), melt peak temperature( T m) and degree of crystallization of PP increase with increasing the grafting rate of FPP. Double melting peaks of FPP with low grafting rate are observed. As grafting rate increases, the double melt peaks convert to a single melt peak. It is suggest that FPP shows a higher nucleation and crystallization ability than that of PP. The thermal stability of FPP increases with increasing the grafting rate. This indicates that the grafting of AA into PP chain improves the thermal stability of PP. The mechanical properties of PP materials can be improved by addtion of FPP. |
