ABSTRACT:
Soluble, curable triazine polymers are prepared by first polymerizing an aliphatic nitrile at a temperature of about 80.degree. to about 450.degree. C in the presence of a catalyst such as a metal chloride to form a B-stage polymer, treating the B-stage polymer with a solvent such as diethyl ether to remove unreacted nitrile and finally extracting the soluble, curable triazine polymer from the thus-treated B-stage material with an alcohol, such as methanol. On heating, the soluble triazine polymers can be cured to form thermally-stable, insoluble, infusible polymeric materials. Thermoplastic compositions may be reinforced with the cured triazine polymer coated reinforcing agents.
