Fluorine-19M1HN nuclear magnetic resonance (NMR) at 188.29 MHz, including 1H ] 19FM1HN crosspolarization (CP) with high-speed magic-angle spinning (MAS), was used to study some Ñuoropolymers of the Viton type. The systems examined were (a) copolymers of vinylidene Ñuoride and hexaÑuoropropene and (b
## Abstract The changes in the conformation and molecular mobility accompanied by a phase transition in the crystalline domain were analyzed for ethylene (E) and tetrafluoroethylene (TFE) copolymer, ETFE, using variable‐temperature (VT) solid‐state ^19^F magic angle spinning (MAS) and ^1^H → ^19^F
