【Abstract】 The general modification methods of polypropylene are introduced, including copolymerization, grafting, crosslinking,filling,strongening and blending. The new technology which nano particles are used for improvement properties of polypropylene is described. The results show that composites of nano particle and PP have good rigidity and impact property under low temperatur.更多还原
