Abstract
Blends of ortho substituted dicyanate esters and unsubstituted dicyanate esters when partially reacted to form co-prepolymers are appreciably lower in viscosity at process temperatures than the homo-prepolymers of a particular dicyante. When cured, the blends exhibit excellent heat and moisture resistance properties. The cured compositions are useful in structural composites, filmed structural adhesives and printed wiring boards.
