## Abstract High resolution fluorine magnetic resonance spectra have been obtained for poly(vinyl fluoride) at elevated temperature. Proton noiseβdecoupling and timeβaveraging techniques have given new tacticity and sequence information.
## Abstract Highβresolution proton magnetic resonance and infrared spectra of poly(vinyl formal) were studied in comparison with those of the model formals obtained from stereoisomers of pentaneβ2,4βdiol and heptaneβ2,4,6βtriol in order to learn spectral changes due to differences of the steric str
