Enantiomerically pure (1) and rucemic (2) methyl-N-( 1-phenylethyl)-2-azabicycld2.2.1 lhept-5-ene-3-carboxylate were found to undergo ring opening metathesis polymerization reactions employing molybdenum alkylidene initiators of the type Mo(CH-t-Bu)(NArXOR), (Ar = 2,6-C,Ha-i-Pr2; R = C(CH,),; C(CH,)
13C NMR spectra of the three title polymers have been determined for polymers of different tacticities. Assignments to the various possible HWHT/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
