| 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 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. |
