Abstract

Polyaryl cyanates have been shown to be useful as thermosetting resins in the manufacture of printed circuit (PC) boards. These materials have good electrical and thermal properties, but their mechanical properties are not satisfactory. The glass-filled pre preg made from this material is brittle. Materials such as bis-maleimide have been added to the formulation to form a resin which has improved processability. The resin system from a mixture of bisphenol A dicyanate and bis-maleimide is not a copolymer but is simply an interpenetrating blend of the two homo polymers. The mechanical properties of this system are dictated by the properties of the individual homo polymers.
