HOMOGENEOUS THERMOSET COPOLYMERS

摘要

Novel compositions of matter comprise homogeneous thermoset copolymers resulting from the reaction between a poly(vinyl benzyl ether) of a polyphenol and a cyanate compound which may be a dicyanate ester of a polyether of a polyphenol or a polyaromatic cyanate compound which 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.
