Notes:
13C NMR spectra of the three title polymers have been determined for polymers of different tacticities. Assignments to the various possible HH/HT/TT and m/r dyad structures were made. These were facilitated by the use of optically active monomers in the case of 1 and 3. In the precursor polymers the cis double bonds in the HH dyads were less readily hydrogenated than those in the other types of dyad. Methyl substitution parameters are summarized for the hydrogenated polymers and their unsaturated trans precursors.
