Curing Phthalonitrile Resins.
Abstract
Polymerization or cure of di-phthalonitrile monomers or prepolymers by a curing agent selected from (a) an acid and an amine, (b) a salt of an acid and an amine, and (c) mixtures of (a) and (b). In a preferred embodiment, the curing agents are amine salts which are reaction products of an aromatic amine and an aromatic sulfonic acid. The use of the novel curing agent's enhances curing rates and results in polymers which have high Tg's.
