| 中文摘要 | in this report, we describe an improved thermal fractionation technique used to characterize the polydispersity of crystalline ethylene sequence length (cesl) of ethylene/alpha -olefin copolymers. after stepwise isothermal crystallization, the crystalline ethylene sequences are sorted into groups by their lengths. the cesls are estimated using melting points of known hydrocarbons. the content of each group is determined using the calibrated peak area. the statistical terms: the arithmetic mean (l) over bar (n), the weighted mean (l) over bar (w) and the broadness index i = (l) over bar (w)/(l) over bar (n) are used to describe the distribution of cesl. results show that improved thermal fractionation technique can quantitatively characterize the polydispersity of cesl with a high degree of accuracy. |
