Abstract: A series of polyurethane/polyepoxide resin (PU/EP = 50/50) interpenetrating polymer networks (IPN) was prepared. The sample of each type differed in the molecular weight (Mw) of the polyol, 30H/2OHratio and NCO/OHratios in the PUcomponet. The extent of mixing of the components in these IPNwas investigated by using electron microscopy, dynamic mechanical analysis and tensile testing. The results show that the extent of interpenetration can be improved by decreasing the Mw of the polyol and increasing the 3OH/2OHratio, NGO/OHratio in the PUcomponent.
