主　　题：PP/POE blend Dynamic mechanical behavior Dispersed phase model Co-continuous phase model 

摘      要：Polypropylene（PP）/ethylene-octene copolymer（POE） blends were prepared with a twin-screw *** dynamic mechanical behavior were systematically *** results show that PP/POE blends are heterogeneities with a partial compatible two-phase structure,the glass transition temperature of PP phases in the blends tends to shift towards high temperature with increasing the POE content,and the glass transition temperature of POE phases shifts towards the low temperature with increasing the PP *** Kerner＇s dispersed phase model and co-continuous phase model can reasonably predict the visco-elasticity of PP/POE blends with different ***,the morphological structure of the blends can be estimated via comparing the predicted DMA behavior with the experimental data.
