PROBLEM TO BE SOLVED: To produce a thick-walled continuous norbornene polymer molding free of curing defects without being affected by the environment at a relatively low equipment cost by supplying a polymerizable composition containing a norbornene monomer and a ruthenium complex catalyst to a pultrusion die and pultruding the composition as a continuous polymer molding. SOLUTION: A ruthenium-carbene complex catalyst of formula I or a ruthenium-vinylidene complex catalyst of formula II is used. The polymerizable composition is polymerized and solidified in a pultrusion die and simultaneously pultruded. In the formulas, R1 and R2 are each H, alkenyl, alkyl, aryl, carboylate alkoxy, alkenyloxy, aryloxy, alkoxycarbonyl or (substituted)alkylthio; X1 to X4 are each an anionic ligand; L1 to L4 are each a neutral electron donor provided two or three groups among X and L groups may combine with each other to form a multidentate chelated ligand; and R3 and R4 are each the same as R1 or R2 or are each a ferrocene derivative. Dicyclopentadiene is the most favorable as the nobornene monomer.
