用解偏振光强法和差示扫描量热法（ＤＳＣ）分别研究了聚甲醛和聚甲醛助剂Ｐ的等温结晶动力学和非等温结晶动力学．探讨了助剂Ｐ对聚甲醛的结晶成核作用．
The isothermal crystallization kinetics and non-isothermal crystallization kinetics of polyoxymethylene (POM) and polyoxymethylene (POM) additive P were studied by means of depolarization intensity method and differential scanning calorimetry (DSC). The crystallization nucleation of POM on POM was discussed.
