## Abstract The examination, by ^1^H NMR, of anionic hydroxytelechelic polybutadienes in conjunction with accurately measured M~n~ values allows the simultaneous determination of the number average functionality and the identification of the nature of the chain ends bearing the functional groups. T
The NMR spectrum of acrolein and acroyl fluoride (CH,=CH-COX with X=H and F) oriented in a nematic phase has been measured and information about conformational equilibrium s-cis s-trans has been obtained. The barrier to internal rotation of the COX group has been studied with various hypotheses. Goo
