| Abstract: | The ethylene-propylene copolymer fractionation; the treated specimens were was pretreated by Soxhlet extraction and temperature-rising elution analyzed with carbon spectrum of nuclear magnetic resonance. The discrepancy in micro-sequential structure was elucidated for the specimens fractionated at different temperatures in TREF process. A method for evaluating the micro-sequential structure was established, which could be used in both the commercial production and scientific development process. |
