Notes:
A simple recording dilatometer was adapted and used to determine or follow the rates of photopolymerization of ethylene glycol dimethacrylate with the isobutyl ether of benzoin as photoinitiator. The photopolymerization was recorded from 0% to 100% conversion of monomer to polymer, and the results from the dilatometer were compared with other methods (gravimetric, electrical resistance, and differential thermal analysis). The rates of photopolymerization were calculated as a function of initiator concentration, light intensity, and monomer concentration. Gel points could be directly determined along with the degree of conversion of monomer to polymer formation. The recording dilatometer can be used to measure rates of photopolymerization of ultraviolet crosslinking monomers, polymers, or coating systems.
