摘要
利用索氏抽提分离、升温淋洗分级对乙丙共聚物进行分级,对分级后的级分做核磁共振碳谱测试。研究了乙丙共聚物的链段存在形式,讨论了不同级分试样结构上的差别,建立了适合工业生产和科研开发过程中评价产品序列结构的方法。
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.
