Novel conjugated ionic polymer was prepared by the polymerization of 2-ethy
nylpyridine with propargyl tosylate in refluxing methyl alcohol. The polyme
rization proceeded well in homogeneous manner to give a relatively high yie
ld of polymer. The resulting poly(2-ethynylpyridinium tosylate) having prop
argyl side chain [poly(EPT-P)] were hygroscopic and soluble in water, methy
l alcohol, DMF, and DMSO. The inherent viscosities of the polymers were in
the range of 0.08-0.29dL/g. Instrumental analyses using NMR, IR, and UV-vis
ible spectroscopies and elemental analyses indicated that the resulting pol
y(EPT-P) have a conjugated ionic polymer backbone carrying N-propargyl-2-py
ridinium tosylate. Thermal and electro-optical properties of the polymers w
ere also studied.
