摘要：The β-crystalline form iPP was prepared by an amine compound NA-WB. The crystallization morphology and behavior of the β-iPP was studied by means of WAXD, DSC and POM. The effect of β-form nucleating agent on mechanical property was also studied. The results show that β-form nucleating agent NA-WB can change the crystal structure, and enhance the crystalline temperature of iPP. The tensile and bend capability decreased a little and the Izod notched impact strength increased by more than 3.5 times from 49.35 J/m to 176.23 J/m due to the addition of 3 mg/g nucleating agent in iPP. The stability of nucleating effect of nucleator on iPP is good.
