摘　　要：介绍了基于示差扫描量热(DSC)的热分级方法的具体热处理过程和对实验结果的数学处理方法,并以支化乙烯聚合物为例讨论了该方法对支化聚合物结晶链段分布结构的表征作用。Thermal segregation of polymers based on DSC was introduced with the general operation procedure and the physical meaning of the results. The method was used to characterize branched ethylene polymers. The results were discussed with the character of each polymer chain structure. It can be ensured that the method was effective to characterize the sequence structure of branched polymers.
