Patent ID: 8722828

Claim:
A process for producing a cycloolefin resin film comprising the steps of: the step (I) of mixing a cycloolefin monomer, a ruthenium complex compound having a hetero atom-containing carbene compound as a ligand, a radical generating agent, and a chain transfer agent to prepare a polymerizable composition (A); the step (II) of coating or impregnating a 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, wherein the hetero atom-containing carbene compound has a hetero ring which includes a carbon atom and hetero atoms bonding to both sides of the carbene carbon atom, wherein the chain transfer agent is one or more selected from the group consisting of aromatic olefins and a compound represented by the formula CH 2 ═CH-Q, wherein Q is a group which has at least one group selected from the group consisting of a methacryloyl group, acryloyl group, vinyl silyl group, epoxy group, and amino group, wherein the supporting body is a metallic foil, resin support film, or fiber material, and the fiber material is one or more selected from the group consisting of glass fiber, carbon fiber, aramid fiber, polyethyleneterephthalate fiber, vinylon fiber, polyester fiber, amide fiber, metal fiber, and ceramic fiber; wherein the step (III) comprises heating the supporting body coated or impregnated with the polymerizable composition (A) to a prescribed temperature using a heating roll, heating plate, or heating oven to polymerize the polymerizable composition (A) by bulk polymerization, wherein the cycloolefin resin film is a post-crosslinkable thermoplastic film or a crosslinked resin film, and wherein the step (III) is carried out continuously and at once after the step (II).
