Polymeric Schiff Bases. I. The Synthesis and Evaluation of Polymeric Schiff Bases Prepared by Schiff Base Exchange Reactions

Abstract
This paper compares the syntheses and the thermal stabilities of twelve related conjugated, pseudoconjugated, and nonconjugated Schiff base polymers of the general formula in which Z represents The polymers were prepared (a) by the condensation of Z(NH2)2 and p-C6 H4(CHO)2 in (1) solution and (2) as melts, and (b) by three new Schiff base exchange reactions: (1) the aldehyde exchange, (2) the amine exchange and (3) the bis exchange
