Mnobs. measured by NMR spectroscopy.
Mnstoich was defined by the monomer to initiator ratio.
Polydispersity indices were determined by SEC in chloroform relative to polystyrene standards.
The percent cis-prop-1-enyl isomer incorporation was determined by 1H NMR spectroscopy.
Solution polymerizations were carried out at 20wt% monomer in diglyme.
Polymerization time of 144 hours.
