    Abstract

    Ring opened metathesis polymerization was carried out on a number of cyclic olefins using Cl2(PCy3)2Ru[CH(Ph)] and [(η6-p-cymene)(PCy3)RuCl(double bond; length as m-dashCdouble bond; length as m-dashCdouble bond; length as m-dashCPh2)]OTf in dichloromethane and a range of ionic liquids. Microstructural parameters were determined from the 13C NMR spectra recorded of the polymers. The findings indicate that an increase in activity of both catalysts can occur in certain ionic liquids systems. It was also observed that the activity of [(η6-p-cymene)(PCy3)RuCl(double bond; length as m-dashCdouble bond; length as m-dashCdouble bond; length as m-dashCPh2)]OTf increases upon addition of an excess of phenol.
