Abstract

Amphiphilic poly(vinyl pyridine) (PVP) with uniform polyoxyethylene (PEO) was synthesized by copolymerization of the PEO macromer with 2-vinyl pyridine in benzene, using AIBN as initiator. The purified copolymer was characterized by IR, 1H NMR and membrane osmometry. The copolymerization conditions were studied. The results show that the grafting efficiency is able to reach 56% and molecular weight of the copolymer can reach 6 × 104. The graft copolymer can, exhibit emulsifying ability and good phase transfer catalytic property in the Williamson reaction. The graft copolymer after complexed with LiClO4 and TCNQ showed ionic conductivity, electronic conductivity and mixed conductivity, respectively. The mixed conductivity showed an obvious synergistic effect.
