Abstract In order to study the effect of polypropylene glycol diglycidyl ether (JH-230) on the basic properties of thermosetting shape memory epoxy resin, a novel shape memory hydrogenated bisphenol A epoxy resin was prepared by the hydrogenated bisphenol A epoxy resin (AL-3040), polypropylene glycol diglycidyl ether (JH-230) and isophorone diamine (IPDA) with different molar ratios between the AL-3040 and the JH-230. The molecular structures of the thermosetting shape memory epoxy resin were mea-sured by the flourier transform infrared spectroscopy (FT-IR), the glass-transition temperature (T_g) of the epoxy resin was studied by the differential scanning calorimetry (DSC), and the corresponding storage modulus and shape memory property were observed by the dynamic thermomechanical analyzer (DMA) and tensile-recovery shape memory test. Results showed that the flexibility of the epoxy resin increased and the T_g of the epoxy resin decreased with increased JH-230 content. The storage modulus of the epoxy resin decreased and the complete recovery time of the epoxy resin extended with increased JH-230 content. It was suggested that the flexibility, T_g and storage modulus of epoxy resin can be controlled by adjusting the JH-230 content, and the shape memory hydrogenated bisphenol A epoxy resin has good shape memory property.

Key words： hydrogenated bisphenol A epoxy resin glass transition temperature storage modulus shape memory property
