<p>A process (1) for producing a cycloolefin resin film comprising the steps of: the step (I) of mixing a cycloolefin monomer and a metathesis polymerization catalyst to prepare a polymerizable composition (A); the step (II) of coating or impregnating the supporting body with the polymerizable composition (A) at once after the step(I), and the step (III) of polymerizing the polymerizable composition (A) by bulk polymerization; and a process (2) for producing a cycloolefin polymer sheet or film with the thickness of 1 mm or less comprising polymerizing a reactive solution containing a ruthenium complex catalyst, having a hetero atom-containing carbene compound as a ligand, and a cycloolefin monomer by ring-opening metathesis bulk polymerization, wherein the polymerization of the cycloolefin monomer is completed by heating the reactive solution to 100 DEG C or higher at the heating rate of 20 DEG C/min or more. Thus, a cycloolefin resin film having excellent adhesion to other materials and a cycloolefin polymer sheet of film having a thickness of 1 mm or smaller can be efficiently produced. <IMAGE></p> |
