<p>The present invention intends to provide a crosslinkable molded article and a crosslinked molded article free from molding failures, wherein their coefficient of thermal expansion is sufficiently low, their dimensional accuracy is high and a polymerizable composition is sufficiently filled in a fibrous material; a process for producing the same; and a use of such molded articles. A process for producing the molded articles of the present invention is characterized by producing a crosslinkable molded article by performing ring-opening bulk polymerization of a polymerizable composition comprising a cycloolefin monomer, a metathesis catalyst and, in accordance with need, a crosslinking agent and/or a filler in the presence of a glass yarn cloth having a bulk density of 0.50 to 1.10 g/cm 3 and, then, if desired, conducting a crosslinking reaction.</p> |
