Di-substituted pyridinium polymers and synthesis thereof

A method of producing a di-substituted pyridinium polymer by microwave-assisted polymn. of a 2, 3, or 4-substituted pyridine monomer of the formula NC5R4- R' -X, wherein R is selected from hydrogen, hydroxyl, and substituted or unsubstituted alkyl, alkoxy, aryl, alkaryl, aralkyl, and alkenyl groups, R' is a linking group, and X is a leaving group. Using this method, di-substituted pyridinium polymer compns. may be obtained wherein at least 50% of the di- substituted pyridinium polymer chains in the compn. have the same degree of polymn. Thus, 3-(7-bromoheptyl)pyridine was prepd. and dissolved in methanol and microwave-assisted polymd. at 130°, 8 bar and 30 w to give an antibacterial hemolytic poly[3-(7-bromoheptyl)pyridine] as a brown oil.
