PROBLEM TO BE SOLVED: To provide a method for producing a molding comprising a polynorbornene resin substantially free from the generation of odors caused by an unreacted monomer, etc., simply at low costs. SOLUTION: The molding comprising the polynorbornene resin is obtained by the reaction injection molding of a reaction liquid containing a norbornene monomer, and the molding is heated at 50-90 deg.C. The molding is preferably heated by air for 0.1-5 h in an oven. |
