A study of the viscosity rise during free radical crosslinking polymerization is presented. Techniques W.ere developed for monitoring isothermal viscosity rise during fast polymerization reactions. The chemical system used composed of a dimethacrylate resin in styrene monomer, t-butyl perbenzoate initiator, and hydroquinone as the inhibitor. W.hen reduced viscosity is plotted versus conversion, data at all temperatures collapsed into a single curve. A theoretical equation is suggested for the time required to reach the gel point in free radical crosslinking polymerization W.ith inhibition. This equation shoW.ed good agreement W.ith experimental observations.
