ABSTRACT:
Printed wiring boards useful for high frequency applications are obtained by laminating a copper foil pretreated with a silane to a polynorbornene prepreg. The prepreg is made by impregnating a fiberglass cloth with a ring-opening polymerized polymer. The copper foil is pretreated with a silane which is capable of improving the bond strength between the copper foil and a norbornene copolymer.
