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.
