The influence of the structural fragments (metal cation, ligand and anion) of metalliferous epoxy chelate polymers (MECPs) on their properties, viz strength, deformation temperature (DT) and thermal oxidative stability, has been examined. Correlations between tensile strength (at) and tensile modulus (Et) and between flexural strength (af) and flexural modulus (Ef), a t = f(Et) and a r = f(E O, have been established. By supposing that, when the conditions at.A = at.B, O'fA. = O'f.B, Et, g = Et,l~ and Ef, A = El, B are fulfilled, where A and B are complex hardeners of partly different structures, the epoxy chelate matrices based on the same oligomer and these complexes have similar structures, the influence of the structural fragments on MECP properties was evaluated. It was found that the effect of chelate structure on the alteration of polymer properties is maximal for thermal oxidative stability(AM is the polymer mass loss after thermal treatment in air), minimal for compressive strength (ac) and decreases in the following order
