Abstract
Novel compositions of matter comprising semi-interpenetrating polymer networks resulting from the reaction between a poly(vinyl benzyl ether) of a polyphenol and engineering condensation thermoplastic may be used as components in a laminate when coated on a reinforcement or substrate. The resulting laminates which may be employed in electric circuit boards will possess desirable electrical and thermal properties as exemplified by a high glass transition temperature and a low dielectric constant.
