Abstract
Alternating copolymerization of isoprene with maleic anhydride was carried out by rare earth coordination catalyst [Nd (naph)(3)-AlEt3] for the first time. The better copolymerization conditions are: [M](total) = 2.6 mol/L, n (Al)/n(Nd) = 10, [Nd] = 5 X 10(-3) mol/L, V(toluene)/V(dioxane) = 2/5 as so lvent, 5 degreesC, 2 h. Copolymer yield was 70%. The copolymer was characte rized by elemental analysis, IR and C-13 NMR.
