摘要：
Sequence analysis of soluble copolymers of various compositions of vinylidene fluoride and tetrafluoroethylene is performed based on F-19 nuclear magnetic resonance spectral intensities at very high field. A new strategy is proposed for the adjustment of a first-order Markov polymerization scheme to the experimental data. Previous line assignments are then discussed and minor lines arising from impurities can be eliminated.
