The cathodic electro-initiated polymerization reaction of the unsaturated polyester prepolymer has been found to have the characteristics of the first order ionic initiation polymerization mechanism. The rate of polymer formation is directly proportional to the current intensity and voltage supplied, but inversely proportional to the reaction temperature. The rate of initiation can be expressed as a function of the initial concentration of the prepolymer, residence time and reaction temperature. The rate expression of the initiation step has been derived based upon the experimental data collected as follows:

ln W = k0 exp[-Ea/RT] Ca0 ln t + ln b

where k0 = 0.257 sec-1

Ea = 1.26 x 102 cal/g prepolymer

b = 1.8 x 10-3 T2 - 1.1 T + 102.37
