本文测定了四氟乙烯(CF_2=CF_2)和3-甲酯基全氟丙基乙烯基醚[CH_3O_2C(CF_2)_3OCF=CF_2]共聚物(以下简称 TFE—PFO 共聚物)的~(19)F NMR 谱,并作了归属。从一组主链上 OF_2峰讨论了序列结构,并测定了共聚物的组成。
In this paper, the determination of ~ (19) F of tetrafluoroethylene (CF_2 = CF_2) and 3-carbomethoxy perfluoropropyl vinyl ether [CH_3O_2C (CF_2) _3OCF = CF_2] (hereinafter referred to as TFE-PFO copolymer) NMR spectra and assigned. The sequence structure was discussed from a set of OF 2 peaks on the backbone and the copolymer composition was determined.
