Abstract

High mol. wt. poly-as-triazines can be prepd. as concd. solns., in which gelling and/or thickening can be avoided, by reacting a dihydrazidine and a bis-(1,2-dicarbonyl) cpd. in a solvent for the poly-as-triazine, the amts. of dihydrazidine and bis-(1,2-dicarbonyl) cpd. reacted being in the proportion 0.975-0.995 mole of one reactant per 1.00 mole of.
