Type: article

Abstract: The control of the microstructures of polymer materials derived from diene‐based monomers is crucial, and various synthetic methods, including anionic, radical, and coordination polymerization reactions, have been extensively explored. Here, we demonstrated the coordination polymerization of 2‐phenyl[3]dendralenes (P3D) as a diene monomer. The polymerization process using monocyclopentadienyltitanium trichloride (CpTiCl3) as a catalyst and modified methylaluminoxane (MMAO) as a cocatalyst (CpTiCl3/MMAO) yielded polymers with an exclusive 4,6‐structure that is distinct from those produced by anionic polymerization. Furthermore, the copolymerization of P3D with isoprene and styrene proceeded randomly.
