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
## Abstract The title monomers 1 and 2 were polymerized by Ruβ, Irβ, Moβ, Wβ and Reβbased metathesis catalysts to yield polymers with __cis__ contents ranging from 10% to at least 90% for 1 and 23β60% for 2. Assignments of the ^13^C NMR spectra were made. No significant headβtail bias was observed
Three new compounds, one with the mo~ecular formula c6&s and hvo COmspOnding to GHloS have been isolated together with the main product, divinyl sulphide, from the reaction products of acetylene with sodium sulphide. Structure determination through 'H and 13C NMR with selective "C4'H) decoupling, sh
