An object of the present invention is to provide a novel poly(cyclic conjugated diene) and a process for producing the same; and a modifying product, a hydrogenated product, and a poly(cyclic conjugated diene) comprising phenylene thereof.
The present invention is a polymer having molecular structure units derived from cyclic conjugated diene monomers having a polar group. The basic skeleton of the molecular structure units of this polymer preferably has a 5-8-membered cycloalkene ring. For polymerizing reaction of the cyclic conjugated diene monomer, it is preferred to use a catalyst such as a Ni-based catalyst, and conduct the reaction in a non-polar solvent containing a basic compound or in an aromatic halide solvent. The Ni-based catalyst is used for the polymerization to obtain a polymer having high crystallizability. Its substituents are removed to obtain a paraphenylene polymer.
