| Abstract: | Ring opening alternating copolymerization of maleic anhydride withPiopylene oxide was conducted by cataiytic system Nd(naph)3-Al(i-Bu)3for the first time to give high yield copolymer of unsaturated polyester.The alternding structure of copolymer was characterized by IR and NMR.The kiodics of the copolymerization was studied. The results indicatedthat the copolymerization rate is first order with respect to both monomer concendation and catalyst concentration. |
