摘要： 使用连续自成核退火法对BOPP专用料的分子链结构进行了表征，在BOPP材料的结晶行为与分子结构之间建立了对应关系。研究结果表明，兰州石化所产牌号为T38F的BOPP树脂的厚晶片与薄晶片的比值Ipeak1/Ipeak2在0.2~0.4，晶片厚度分布系数在1.052~1.071。该方法具有设备简单、操作简便、样品量少、耗时短等优点，可用于BOPP专用料生产中对分子结构的实时监控。

Abstract: The molecular chain structure of BOPP special materials was characterized by successive self-nucleation and annealing (SSA) thermal analysis using DSC, and co-relation between crystallization behavior and molecular structure was established. The research results show that the value of Ipeak1/Ipeak2 in BOPP resin produced by Lanzhou petrochemical company ranges from 0.2 to 0.4, and the parameters of the distribution ranges from 1.052 to 1.071. This method have the advantages of time-saving and cost-saving, and which can be used in real-time monitoring of molecular structure.
