Simultaneous full interpenetrating polymer networks of poly(diethyleneglycol bis(allylcarbonate)) and poly(urethane acrylates) have been synthesized and characterized by the measurement of mechanical properties, fracture toughness parameters, and by dynamic mechanical analysis. No evidence of phase segregation was detected in the interpenetrating polymer networks. The networks exhibited a single glass transition temperature at all the compositions studied. Significant enhancement in mechanical properties and fracture toughness was observed in one of the interpenetrating polymer networks which was characterized by high chain intermixing. The high optical transparency of the base resin system was retained in all the interpenetrating polymer network systems studied.
