Abstract
Dielectric supports for electronic components, such as circuit boards, are provided which are comprised of two or more bulk polymerized norbornene-type monomers. The monomers may be easily processed into circuit boards, etc. by reaction injection molding. The copolymers obtained exhibit high heat distortion temperatures and good dielectric properties and a balance of properties that make them, for example, well suited for molded wire board materials.
