Abstract

PURPOSE: To prepare a ring opening polymer with high yields by ring opening polymerization of norbornadiene derivatives, etc. by the use of a catalyst system obtained from a reaction product of an organometallic compound, an oxide of W and/or Mo and a Lewis acid and a reactive group-containing polymer.
