Vinylester resin containing styrene is used for the materials reclaiming sewerage pipes. However, styrene is limited to use due to environmental problem in fabrication. Therefore, alternative resin is desired. Since sewerage pipes is subjected to soil pressure for a long time in service, long period creep property should be estimated in advance. In the present study, long period creep properties of vinylester resin containing monofunctional methacrylate as a candidate of alternative resin were evaluated. Short term creep tests under higher temperature were carried out and master curves were obtained using time-temperature superposition principle (TTS). We estimate the applicability of TTS for vinylester resins comparing with the results of 1,000 hour creep tests under room temperature. The results showed that TTS could be applicable for vinylester resins and the resins containing monofunctional methacrylate (monomer/ester=1.0/1.5, 1.5/1.0) had higher durability than conventional one.
