Abstract

In this article,Fe(acac)_3-Al(i-Bu)_3 was first used to catalyze copolymerization of maleic anhydride and isoprene.When the reaction was carried in V(T)/V(D)=2/5(T: dioxane;D: toluene) in 2 h under nitrogen atmosphere,the yield was(78.3%).The solvent experiments indicated that the copolymer didn′t solve in chloroform,acetone,THF and so on.When the copolymer was obtained in polar solvent such as dioxane,however,it could solve in THF slightly.The structure and composition of the copolymer were characterized by IR,NMR and elementary analysis.
