NMR analysis of the Kel-F co-polymer system. Period covered: July--September 1976
1976
Abstract
Dimethylacetamide solutions of several members of the Kel-F polymer system were analyzed by /sup 19/F NMR spectrometry. Although relatively acceptable spectral data are obtained, the mandatory methods of analysis for this type of system, such as reliable peak integration data and data time averaging, are not possible with the limited lock mode sweep range of the Varian HA-100 (1500 Hz). The possibility of electronic modification of the unit for the purpose of increasing the lock mode sweep range to cover the /sup 19/F spectral range is being studied.
