摘要 Thethermallystimulatedshapememorybehaviorofethyleneoxide-butyleneterephthalate(EOBT)segmentedcopolymerswithdifferentsoftsegmentmolecularweightandhardsegmentcontentwasinvestigated.ThedeformationrecoveryratioR_foftheEOBTsamplesincreaseswiththesoftsegmentmolecularweightandthehardsegmentweightcontent,whiletheaverageoveralldeformationrecoveryspeedV_rincreaseswiththehardsegmentcontent.Thetemperatureofmaximumdeformationrecoveryspeed(T_M)isdeterminedbythemeltingtemperatureofthesoftsegmentcrystalsandthestabilityofthecrystallizedhardsegmentdomains.
