<P>PROBLEM TO BE SOLVED: To provide a film which includes a thermosetting crosslinked cyclic olefin resin obtained by ring-opening metathesis polymerization of a cyclic olefin monomer and has a sufficient mold-releasability with resins used as a sealing material, a prepreg and an adhesive and mechanical strength such as tensile elongation at break and tensile strength at break, and to provide a method for producing the same. <P>SOLUTION: The thermosetting crosslinked cyclic olefin resin film can be obtained by ring-opening metathesis polymerization of a polymerizable composition which includes (a) 100 pts.mass of a cyclic olefin monomer and (b) 0.5 to 8 pts.mass of a polymer that includes 100 to 20 mass% of alkyl(meth)acrylate units wherein the alkyl has three or more carbon atoms and 0 to 80 mass% of aromatic vinyl compound units or alkyl(meth)acrylate units wherein the alkyl has two or less carbon atoms and that has a weight-average molecular weight of 2,000 to 2,000,000. <P>COPYRIGHT: (C)2012,JPO&INPIT |
