AbstractNorbornene polymerization was first carried out by (dienzoylmethanato)(2) Ti (OPh)(2) [(dbm)(2) Ti (OPh)(2)]/ methylaluminoxane (MAO), a type of beta -diketonate titanium non-metallocene catalytic system. A mixture of vinyl addition polymer and ring-opening metathesis polymer was obtained. Polymer structure was characterized by FTIR. Influence of polymerization temperature, Al/Ti mole ratio, monomer concentration and solvents on polymerization activity as well as on polymer structure was investigated. Higher activity was achieved at 80 degreesC with higher Al/Ti mole ratio and monomer concentration as well as 1,2-dichlorobenzene as the solvent instead of toluene. Higher temperature, higher Al/Ti mole ratio, lower monomer concentration have the advantage of forming more ring-opening polymer structure and less addition polymer structure.
