Abstract

Epoxy based shape memory polymer was developed by curing the epoxy resin, Diglycidyl Ether of Bisphenol A
(DGEBA) with 4,7,10 trioxa-1,13-tridecanediamine (TTD). The viscoelastic behavior of the SMEP was
evaluated using an Advanced Rheometric Expansion System (ARES). The well known Time Temperature
Superposition (TTS) principle was applied to generate the master curve by selecting loss modulus peak as glass
transition temperature (Tg). The two constants, C1 and C2 of the Williams Landel Ferry (WLF) equation were
determined and they have been compared with the universal constant values for amorphous polymer. The
results obtained from these studies have been reported in this paper which is useful inputs for predicting the
shape memory behavior of the SMEP.
