Abstract
Ionic conjugated polymer, poly(2-ethynyl-N-propargylpyridinium bromide), wa s prepared by the cyclopolymerization of 2-ethynyl-N-propargylpyridinium br omide on using various transition metal catalysts, or by thermal methods wi thout adding catalyst. The polymerization of 2-ethynyl-N-propargylpyridiniu m bromide catalyzed by PdCl2 gave the resulting polymers in relatively high yields. The polymer structure was characterized by various instrumental me thods to confirm the conjugated polymer backbone structure carrying cumulat ed pyridine moiety. The polymers prepared by PdCl2 in DMSO or m-cresol were completely soluble in DMF, DMSO, and formic acid. The inherent viscosities of the resulting polymers were in the range of 0.07-0.19 dL/g. Thermal pro perties of the polymers were also discussed.
