Apparent activation energies for curing reactions in unsaturated polyesters in the presence of ferrocene or ferrocene derivatives

Abstract

This paper presents the results obtained on measuring the apparent activation energies of hardening reactions in unsaturated polyesters running on using various monosubstituted and 1,1′-disubstituted ferrocene derivatives as accelerators. It has been found that the apparent activation energies of these reactions can be correlated with the literature values of quarter-wave potentials E 1 4 for individual ferrocene derivatives. On the contrary the activation energies have not been found in any relation to the relative molecular masses of the accelerators concerned.
