【Abstract】 The alternating copolymerization of maleic anhydride with styrene oxide catalyzed by Fe(acac) 3-Al-(i-Bu) 3 was studied. The suitable copolymerization conditions were found at: [MA]=2.28 mol/L, [MA]∶[SO]=1∶1, [Fe]/[Al]=1∶8,and [Fe]=2.87×10 -2 mol/L. Respectively, yield was 59.1% at 80 ℃ in toluen. Meanwhile, the structure of copolymer was characterized by IR and 1H-NMR, and the kinetics of the copolymerization indicates that the copolymerization rate is in first order with respect to the concentrations of both monomers.更多还原
