摘要：The terpolymerization of ethylene and propylene with isoprene was performed catalyzed by half-sandwich scandium complexes (C5Me4SiMe3)Sc(CH2SiMe3)(2)(THF) (1) and [1,3-(Me2Si)(2)C9H5]Sc(CH2SiMe3)(2) (THF) (2) in combination with 1 equiv. of [Ph3C][B(C6F5)(4)]. The terpolymers with ethylene contents of 60-84 mol% and isoprene contents of 5-26 mol% (1,4/3,4 approximate to 50/50) were obtained in the presence of complex 1. In comparison, the terpolymers with ethylene contents of 38-75 mol% and isoprene contents of 4-43 mol% (1,4/3,4 approximate to 70/30) were obtained in the presence of complex 2. Subsequently, a functionalized ethylene-propylene-isoprene terpolymer was prepared by the epoxidation of the 1,4-isoprene units in the terpolymer backbone and further hydroxylation/chlorination through ring-opening reaction of the epoxy groups.
