摘要
用１３Ｃ－ＮＭＲ、Ｘ射线衍射、ＤＳＣ和ＤＭＡ技术，对不同批次的乙丙嵌段共聚物进行了表征，发现它们的分子链是以长的乙烯、丙烯链为主，并含有其它序列结构，而各样品的序列分布不同，显示出不同的物理性质．在此基础上讨论了其结构与性能之间的关系．
thylene-propylene block copolymers taken from different batches were charcterized by means of 13C-NMR, X-ray, DSC, DMA, etc. It is found that their molecular chains consist mainly of ethylene and propylene with a small number of other sequencestructures. The different distributions of the sequence structures in samples exhibit different physical properties. and based on this is the study on the relationship between structures and properties.
