Crysalline shape and behavior were investigated by polarizing microscope and wide angle X-ray diffraction spectrum.The results show that the value of impact strength is maximum while tensile strength,flexural strength,modulus and vicat softening temperature are least when the content of β form nucleator is 0.05 phr.

结果表明，当β成核剂的含量在0.05份时，冲击强度达到最大值，而拉伸强度、弯曲强度、模量、维卡软化温度等达到最小值；当β成核剂含量为0.05份以下时，随着β成核剂含量增加，PP中β晶结晶度大幅度上升，同时α晶结晶度大幅度下降；增加β成核剂用量至大于0.10份时，β晶结晶度略为下降，而α晶结晶度上升，但总结晶度随着β成核剂含量增加呈现上升趋势。
