Recently copolymers containing cyclic hydrocarbon structure are paid great attention for its high transparency, heat resistance, and low dielectric constants. One of the most promising monomer to synthesize these kinds of polymers is norbornene, which is polymerized by either of ring-opening metathesis polymerization or coordinated insertion polymerization. In our contribution, we developed a living coordination polymerization system using ansa-fluorenylamidotitanium complex as a catalyst and applied it to the norbornene homopolymerization and random copolymerization with ethylene, propylene, 1-alkene and styrene. Block copolymerizations with propylene, 1-octene, norbornene and methyl methacrylate are also described.
