| Abstract: | A series of polyurethane/epoxy resin(PU/EP)IPN were prepared.The IPN exhibited single glass transition temperatures in high temperature regions estimated by DSC,TMA and dynamic viscoelastomer.The correlation of phase behavior of IPN and their breaking tensile strength was discussed.Results revealed that existence of the graft copolymer accounted for enhancing interpenetrating effects of the IPN. |

| Keywords: | polyurethane / epoxy resin IPN phase behavior breaking tensile strength |
