Coordination polymerization of (Z)-1-phenyl[3]dendralene by a neodymium catalyst

The control of the microstructure of polymers derived from conjugated dienes was investigated using coordination polymerization. In this work, we conducted coordination polymerization of (Z)-1-phenyl[3]dendralene (1Z-P3D) as a diene monomer. The polymerization of 1Z-P3D using a homogeneous neodymium catalyst yielded poly(1Z-P3D) with predominantly 4,6-structures (~100%). Coordination polymerization of (Z)-1-phenyl[3]dendralene(1Z-P3D) was investigated using by homogeneous neodymium catalyst. The polymer was obtained under the appropriate polymerization condition and the most part of polymer became insoluble in the progress of isolation. The microstructure of poly(1Z-P3D) prepared by neodymium catalyst was only 4,6-structure whereas poly(1Z-P3D) prepared by anionic initiator contained a predominant amount of 1,4-structure.
