  elastomer toughening mechanism of PP: 1) the elastomer PP toughness higher than that of matrix, when the continuous phase as the dispersed phase distribution in PP elastomer, the formation of "sea island structure", when the blend by external effect, elastomer particles as stress concentration, it preferred the distortion under the impact, if two phase interface bonding is good, can lead to generate a lot of silver particle area grain and shear zone and energy consumption, elastomer particles at the same time also can block, steering and terminate small crack development, makes the toughness of the system increases; On the other hand, the addition of elastomers destroyed the crystallization of PP, resulting in the refinement of PP spherulites, and the elastomers played the role of heterogeneous nucleation to toughen the PP.
