The　ring-opening　copolymerization　reaction　(ROCOP)　of　epoxides　and　epoxy　anhydrides　plays　a　crucial　role　in　the　preparation　of　polyesters.　An　amino-modified　metal-organic　framework　material　UiO-66-NH2　was　synthesized　from　hydrothermal　reaction　of　zirconium　tetrachloride　and　2-aminoterephthalic　acid,　and　then　used　as　main　catalyst,　with　co-catalyst　bis(triphenylnorphosphine)ammonium　chloride　(PPNCl),　to　form　a　binary　Lewis　acid　base　for　catalyzing　the　ROCOP　of　epoxidized　epoxycyclohexane　(CHO)　and　maleic　anhydride　(MA).　The　UiO-66-NH2　was　characterized　by　FTIR　and　XRD.　The　effects　of　main　catalyst　type,　reaction　temperature　and　catalyst　dosage　on　CHO　conversion,　polymer　ester-bond　content　and　catalyst　turnover　frequency　were　evaluated　by　1HNMR,　with　the　reaction　kinetics　and　universality　of　monomers　discussed.　And　the　recycling　performance　of　UiO-66-NH2　was　analyzed　by　SEM,　XRD　and　ICP-OES.　The　results　showed　that　the　polyester　P(MA-CHO)　prepared　under　the　conditions　of　PPNCl　(33.2　mg)　as　co-catalyst,　n(UiO-66-NH2)∶n(PPNCl)∶n(MA)∶n(CHO)=1∶1∶100∶100,　reaction　temperature　80　℃　and　reaction　time　1　h　exhibited　excellent　performances,　with　an　ester-bond　content　of　up　to　70.0%,　a　CHO　conversion　of　78.6%,　and　a　catalyst　turnover　frequency　of　78.6　h–1.　The　UiO-66-NH2/PPNCl-catalyzed　ROCOP　of　MA　and　CHO　was　a　first-order　kinetic　reaction　with　an　apparent　activation　energy　of　66.51　kJ/mol.　UiO-66-NH2　could　be　reused　three　times　with　a　slight　decrease　in　catalytic　activity,　with　the　conversion　of　CHO　reduced　from　78.6%　to　77.5%.　©　2025　Fine　Chemicals.　All　rights　reserved.
