In particular, the invention relates to addition poly- merization of vinyl pyridine monomers, comprising zwitterions and carbon-carbon linkages and to a method of preparing the same via a base or nucleophile initiated polymerization. In specific embodiments, zwitterionic homopolymers of 4-vinylpyridine propane- sulfonate (4VPPS), 2-vinylpyridine propanesulfonate (2VPPS) or 4- vinylpyridine propanesulfate (4VPPSa) and block copolymers of 2VPPS and 4-vinylpyridine butanesulfonate (4VPBS) were obtained via nucleophilic addition polymerization reaction in an aqueous cc or polar medium at ambient and atmospheric conditions initiated by base nucleophiles such as N,N,N',N\",N\"-pentamethyldiethylen- etriamine (PMDETA), triethylamine (TEA), 4-(dimethylamino)pyridine (DMAP), N-(4-vinylbenzyl)-N,N-dimethylamine (VBDMA), 00 N,Ndiethylamine (DEA), propylamine (PA), sodium hydroxide (NaOH), 1 -vinylimidazole (VI), sodium methoxide (NaOH), triph- O enylphosphine (Ph3P), sodium phenoxide (NaOPh), or sodium azide (NaN3).
