Abstract: | The thermally stimulated shape memory behavior of ethylene oxide-butylene terephthalate (EOBT) segmentedcopolymers with different soft segment molecular weight and hard segment content was investigated. The deformationrecovery ratio R_f of the EOBT samples increases with the soft segment molecular weight and the hard segment weightcontent, while the average overall deformation recovery speed V_r increases with the hard segment content. The temperatureof maximum deformation recovery speed (T_M) is determined by the melting temperature of the soft segment crystals and thestability of the crystallized hard segment domains. |
