摘要：

Polyamidines with both nitrogens in the main chain (-X-NH-CR=N-) were obtained by polycondensation of diamines with different orthoesters. The thermal properties could be tailored by the choice of diamine and orthoester. Quantitative formation of a cyclic trimer could be observed when 2,6-diaminopyridine was converted with triethyl orthoformate. H-1, C-13 and N-15 NMR spectroscopic investigations in solution and in solid state showed that the configuration of the amidine group was strongly dependent on the residue R. In polyformamidines, strong interactions caused by hydrogen bonds could be evidenced.
