摘要：
The thermally stimulated shape memory behavior of ethylene oxide-butylene terephthalate (EOBT) segmented copolymers with different soft segment molecular weight and hard segment content was investigated. The deformation recovery ratio Rf of the EOBT samples increases with the soft segment molecular weight and the hard segment weight content, while the average overall deformation recovery speed VT increases with the hard segment content. The temperature of maximum deformation recovery speed (TM) is determined by the melting temperature of the soft segment crystals and the stability of the crystallized hard segment domains.
