SYNTHESIS OF POLYELECTROLYTIC POLYACETYLENE DERIVATIVES BY QUATERNIZATION OF POLY（PYRIDYLACETYLENE）

Functional polyacetylenes containing pyridinium side groups（PPyA-MX,X = Br and I） were successfully synthesized.Spectroscopic techniques such as ^1H-NMR,^（13）C-NMR,and FTIR spectroscopy were used to characterize the structure of the obtained polymers.The characterization data were well consistent with the expected macromolecular structures.PPyA-MI had good solubility in polar organic solvents and low solubility in water,while PPyA-MBr had good solubility in both polar organic solvents and water.
