Abstract
Compositions comprising a polyepoxy compound (preferably bisphenol A diglycidyl ether) and a polyphenylene ether which has been melt processed (e.g., by extrusion) at a temperature in the range of about 230.degree.-390.degree. C., are cured at temperatures in the range of about 190.degree.-250.degree. C. by various epoxy cure catalysts. They may used in the preparation of laminates with excellent dielectric properties, solvent resistance and solder resistance, useful in printed circuit board production.
