The effect of sorbitol nucleator ZC-3 on the p roperty of
PP /poly ( ethy2 lene2octene) ( POE) blend and the crystallization
morphology and behavior of the blend were studied bymeans
ofWAXD and DM LP.The results showed the addition of the
nucleator not only increased the toughness of the blend, but also
improved the rigidity of the blend, which balanced the mechanical
properties of the blend.The addition of the nucleator decreased
the spherulite size significantly, and made POE more uniformly
dispersed in PP.The optimum amounts of POE and ZC-3 were
10% , 0.3% (mass fraction) respectively.
