Abstract
The ring-opening metathesis polymerization of a series of cycloalkenes initiated using well defined Schrock-type initiators is described. Th e products have been characterized by gel permeation chromatography, n uclear magnetic resonance and differential scanning calorimetry. The i nfluence of initiator, reaction conditions and monomer structure is an alysed in detail. The detailed microstructures of the polymers can be deduced from the C-13 nuclear magnetic resonance spectra and apparent anomalies are accommodated in terms of the gamma-gauche effect establi shed by Tonelli.
