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Ipeak1/Ipeak2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。
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 Ipeak1/Ipeak2 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.
