## Abstract The three title monomers were polymerized using a variety of Ruβ, Irβ, Moβ, Wβ and Reβbased metathesis catalyst systems to yield polymers having a wide range of __cis__ double bond contents in each case. The ^13^C NMR spectra of the polymers were interpreted in terms of __cis/trans__, h
## 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
