Abstract
The spin-lattice 13C relaxation times and the amplification factors due to the nuclear Overhauser effect are measured in solutions of poly[vinyl(1-adamantyl)carboxylate] and poly[vinyl(2-adamantyl)carboxylate] at frequencies of 25.14 and 62.9 MHz over the temperature range 298–358 K. The experimental results are analysed within the framework of models using empirical distributions of inter-molecular motion correlation times. The activation energies of the polymer chain internal motions are determined. It is established that the type of substitution in the polyhedral radical hardly effects the nature of the main chain motion, but is a decisive factor in determining the rotational freedom of the adamantane group.
