Fully aromatic and aromatic-aliphatic polyformamidines were prepared by high-temperature solution polycondensation of the appropriate diamines with triethyl orthoformate (TEOF). Copolyformamidines of benzidine (4,4'-biphenyldiamine) with p-phenylene and trans-l,4-cyclohexylene units, respectively, s
## Abstract The condensation reactions of the structurally similar monomers 1,3‐phenylenediamine (1a) and 2,6‐diaminopyridine (1b) with triethyl orthoformate have been compared. Whereas the reaction of 1a resulted in an oligomeric polyformamide, a cyclic trimer was obtained almost quantitatively wh
