Summary

13C-NMR spin-lattice relaxation (T1) measurements on syndiotactic and isotactic polymethallylalcohols and poly-(S)-N-1-phenylethylurethanes demonstrate a lack of dependence of T1 on tacticity. On the other hand, the T1-values show a hindered motion of the -CH2OH side chain, which is explained by hydrogen bonding. In an Arrhenius type plot the enthalpy of motion is found to to be very similar for the different groups of polymethallylalcohols, pointing to a common set of motions. The circular dichroism of the polymethallylurethanes is similar to the model compound (S)-N-1-phenylethyl-neopentylurethane, indicating a lack of conformational restrictions of the outer part of the side chains by a polymer effect.
