Abstract

Interpenetrating polymer networks (IPNs) composed of poly(methacrylate) and epoxy-amine networks made in situ between two oriented polypropylene sheets were examined in terms of their oxygen barrier and adhesion to the substrate properties. A particular attention was devoted to a system presenting an obvious phase separation in order to establish a correlation between IPN morphologies and gas barrier properties. Kinetics of formation and phase behavior were investigated by infrared and UV-visible spectroscopy, respectively. Since the poly(methacrylate) network could be instantaneously generated by photoirradiation, IPNs differing in network sequence formation were prepared : by varying the moment of irradiation a difference in IPNs structure was expected. Oxygen transmission rates (OTR) of different films irradiated before and after demixion were measured. It was shown that similar OTR are obtained whatever the moment of irradiation.
