APPARENT ACTIVATION-ENERGIES FOR CURING REACTIONS IN UNSATURATED POLYESTERS IN THE PRESENCE OF FERROCENE OR FERROCENE DERIVATIVES

This paper presents the results obtained on measuring the apparent act ivation energies of hardening reactions in unsaturated polyesters runn ing on using various monosubstituted and 1,1'-disubstituted ferrocene derivatives as accelerators. It has been found that the apparent activ ation energies of these reactions can be correlated with the literatur e values of quarter-wave potentials E1/4 for individual ferrocene deri vatives. On the contrary the activation energies have not been found i n any relation to the relative molecular masses of the accelerators co ncerned.
