摘　　要：研究了β晶型成核剂对聚丙烯管材料力学性能和结晶行为的影响。研究表明,β晶型成核剂的加入大幅提高了聚丙烯管材料的常温冲击强度,材料的结晶形态由原来的以α晶型为主转变为以β晶型为主。The influences of β-nucleating agent on mechanical properties and crystallization behavior of PP pipe resin were studied. The results show that the Izod notched impact strength in normal temperature of PP pipe resin is largely enhanced after adding β-phase nucleating agent, the crystalline form of PP pipe resin is greatly changed from α-phase to β- phase.
