Based on the Hammett equation, a general method is established to relate the polycondensation monomer reactivity with both the monomer structural parameters and the properties of the solvent used for the non‐equilibrium ternary copolycondensation to give copolyamides. Linear plots of the logarithm of the monomer reactivity ratio, log r , versus structure parameter Δp K could be represented by the equation log r = ρ Δp K .Relationship between log r and Δp K using THF as the solvent.
