Shape　memory　polymers　(SMPs),　as　a　type　of　smart　material,　play　a　significant　role　in　practical　applications.　Unlike　the　hot　programming　of　SMPs,　the　cold　programming　of　SMPs　does　not　require　preheating.　They　can　undergo　deformation　and　fix　a　temporary　shape　at　a　specific　temperature　and　can　be　restored　upon　heating.　SMPs　typically　require　internal　cross-linking　to　“remember”　their　permanent　shape.　However,　cross-linked　materials　cannot　be　recycled,　resulting　in　resource　waste　and　environmental　pollution.　Drawing　inspiration　from　dynamic　covalent　cross-linking　technology,　for　the　first　time,　this　paper　integrates　the　cold-programmed　shape　memory　effect　into　thermadapt　SMPs　with　syndiotactic　1,2-polybutadiene　(SPB)　as　the　matrix.　To　construct　a　thermadapt　SMPs,　this　paper　first　obtained　epoxidized　syndiotactic　1,2-polybutadiene　(ESPB)　by　epoxidizing　SPB.　Then,　ESPB　was　mixed　with　carboxy-terminated　liquid　polybutadiene　rubber　(CTPB),　resulting　in　the　formation　of　β-hydroxyl　ester　dynamic　bonds　within　the　material.　By　regulating　the　internal　cross-linking　structure,　its　glass　transition　temperature　(Tg)　can　be　controlled.　Furthermore,　the　molecular　chain　of　the　composite　has　a　regular　structure　that　enables　stretching-induced　crystallization.　This　enhances　the　material’s　ability　to　retain　its　temporary　shape　during　cold　programming.　This　paper　provides　a　feasible　and　straightforward　approach　for　the　preparation　of　recyclable　thermadapt　SMPs　with　cold-programmed　shape　memory　effect　and　paves　the　way　for　the　recycling　and　long-term　utilization　of　SMPs.　©　2023　American　Chemical　Society.
