摘　　要：用差示扫描量热计(DSC)研究了松香型成核剂、山梨醇成核剂和有机磷酸盐类3种有机透明成核剂成核PP的非等温结晶行为。结果表明:3种透明成核剂能显著增加PP的结晶温度,松香型透明成核剂提高PP的结晶速率最大,有机磷酸盐类透明成核剂成核PP的结晶活化能最小,而其结晶成核能力最强。The non-isothermal crystallizition behavior of polypropylene which filling three types nucleating agent under different cooling rates was studied by means of differential scanning calorimetry（DSC）. The results showed that the crystalling temperature of PP filled three types nucleating agent could be impoved and the the crystalling temperature of PP filled rosin type nucleating agent was improved most greatly. Crystallization activation energy of PP filled organic phosphate nucleating agent was the smallest and its erystalling nucleation ability was the strongest.
