ABSTRACT:
Bis-phthalonitrile resins are cured using ionic metal phthalocyanine acceators. The ionic metal phthalocyanines are nontoxic and accelerate the cure rate of the resins without adversely affecting cured polymer strength. Di-Na, di-Li, Mg and Cd phthalocyanines in particular provide excellent cure acceleration. Also, the metal phthalocyanine can be made soluble in the resin by appropriate substitution of the aromatic rings, thus providing for homogenous polymerization.
