Using the method of attenuated total internal reflection, infra-red spectroscopy has been used to study the kinetics of formation of the interpenetrating polymer network (IPN) formed between polyurethane and polyesteracrylate. It was found that the curing rates of the different networks are related and an increase in the polymerization rate of oligoesteracrylate leads to changes in the rate of polyurethane formation in IPN. The effects observed are explained in terms of the interdependence of the processes of network formation and microphase separation. The degree of segregation of the components in the IPN depends on the rate of formation of each of the networks.
