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.
