A polyester/polyurethane interpenetrating polymer network (IPN) was prepared from acetoxy terminated unsaturated polyester(FUPR) and crosslinked polyurethaiie pre-polymer. The kinetics of network formation, behavior of rnicrophase separation and mecha-nical properties of the IPNs were examined by IR,DSC,and SEM. The results showed that the IPN was formed at a certain ratio of FUPR/PU. The products showed an improved ri-gidity to polyutrethane and increased impact strength to unsaturated polyester.
