摘要
采用连续退火热分级方法表征了聚乙烯大分子链的多分散性 ,同时研究了退火对PE结晶度及力学性能的影响。利用一种新的热分析技术———调制式DSC(MDSC)
The macromolecular chain polydispersity of two kinds of polyethylene was characterized by successive self-nucleation/annealing thermal fractionation and annealing techniques using DSC.The effects of annealing on the crystallinity and mechanical properties of polyethylene were studied.The possible macromolecular motion mechanism and the changing characteristics of crystalline structure of polyethylene during annealing were also investigated via a new thermal analysis technique-modulated DSC.
