Abstract
Novel compositions of matter comprise homogeneous thermoset copolymers resulting from the reaction between a poly(vinyl benzyl ether) of a polyphenol and a dicyanate ester of a polyether of a polyphenol may be used as components in laminates which are employed in electronic circuit boards. The copolymers will impart desirable characteristics such as high glass transition temperatures and low dielectric constants to the finished product.
