ABSTRACT:
Homogeneous thermoset terpolymers which may be used in the preparation of laminates for circuitry boards will comprise a diepoxide of a polyether of a polyphenol, a dicyanate ester of a polyether of a polyphenol and an alkenyl aryl compound. The polymers are prepared by admixing a solution of the diepoxide of a polyether of a polyphenol and an alkenyl aryl compound with a second solution of the dicyanate ester of a polyether of a polyphenol and the alkenyl aryl compound at elevated temperatures. The resulting terpolymer will possess desirable characteristics such as high glass transition temperature and low dielectric constant.
