Abstract

PURPOSE: To prepare a stabilized, almost colorless ring-opened polymer almost free from the lowering of the physical properties, by ring opening-polymerization of a norbornene-type compound in the presence of a specific catalyst containing a transition metal compound, and treating the polymer with an epoxy compound.
CONSTITUTION: (A) A norbornene derivative having one or more polar groups or a ≤20C hydrocarbon group substituted with an aromatic hydrocarbon or a polar group, (B) a cycloolefin compound (≤50 mole% on the basis of (A)), and if necessary (C) an unsaturated polymer (e.g. butadiene rubber, etc.) are polymerized in the presence of a catalyst system comprising (D) an organometallic compound containing one or more metals from I-A to IV-B group in the periodic table (e.g. triethylaluminum, etc.), (E) a transition metal compound (e.g. tungsten trioxide, etc.) and if necessary (F) an electron donative compound (e.g. phosphorus pentachloride, etc.). The resultant polymer is treated with (G) an epoxy compound to give the desired polymer.
