PRODUCTION OF COPPER-CLAD LAMINATED BOARD

摘要

PROBLEM TO BE SOLVED: To easily produce a copper-clad laminate board having an insulating layer of cycloolefins by using a molding material produced by using a specified metathesis polymerization catalyst. SOLUTION: A copper-clad laminated board having an insulating layer of cycloolefins is formed by a process in which a semi-cured curable molding material is manufactured by reacting metathesis-polymerizable cycloolefins in the presence of a metathesis polymerization catalyst, after copper foil is arranged at least on one side of the molding material, heated and pressed. Norbornens having at least two rings or at least one selected from >=4C monocyclic cycloolefins are used as the cycloolefins. A polymerizable composition containing cycloolefins and the catalyst can produce a copper-clad laminated board by a usual press molding machine and can be molded without attaching a special apparatus for shutting out oxygen and water in air which hinder the polymerization to the molding machine.
