✦ Synopsis
The ternary copolymers of poly(ethylene oxide) (PEO), terephthaloyl chloride (TPC), and lithium 2,5-diaminobenzene sulfonate (LDABS) have been synthesized by the separated copolymerization PEO, TPC, and LDABS. Three ternary copolymers, PEO 0.12 -TPC 0.50 -LDABS 0.38 , PEO 0.24 -TPC 0.50 -LDABS 0.26 and PEO 0.36 -TPC 0.51 -LDABS 0.13 , are thermally stable and mechanically strong ionic conductors. The combination of immobilized anionic groups (SO 0
3 ) incorporated into the copolymer to increase the mobile cation concentration and of PEO introduced to enhance ionic conductivity via flexible chain motion. PEO 0.24 -TPC 0.50 -LDABS 0.26 was found to be a good polymeric material with good mechanical properties and a high ionic conductivity of 8.37 1 10 06
