Advances in preparation of cycloolefin polymers by ring-opening metathetic polymerization

Based on the methods for cycloolefin copolymers (COC) preparation and their characteristics introduced, the mechanism of carbine catalysts (emphatically Grubbs' catalyst) for the ring-opening metathetic polymerization (ROMP) and the influences of catalyst's ligands and polymeric conditions on the polymerization rate and product properties are reviewed. Furthermore, the catalysts for hydrogenation of many residual C = C in ring-opening products and their properties are also introduced.
