Polymerization of vinylpyridinium salts. X. Copolymerization studies of cationicanionic monomer pairs

Abstract: The mechanism of the spontaneous polymerization of vinylpyridinium salts in aqueous and acidic solution has been actively investigated in recent years. Recent reports have suggested that these reactions are free radical in nature. In order to investigate the involvement of free radical initiation in the spontaneous polymerization reactions, an investigation of ion pair copolymers between the cationic 4‐vinylpyridinium moiety and the anionic vinylsulfonate, 2‐acrylamido‐2‐methylpro‐panesulfonate, and p‐styrenes… Show more

“…showed that attractive Coulombic forces between monomers can result in an increased degree of alternation in copolymers. [83][84][85][86] Combinations of protonated 4-vinyl pyridine and p-styrenesulfonate, 2-methacryloyloxyethyltrimethylammonium and 2-methacryloyloxyethanesulfonate or 3-acrylamido-3-methylbutyltrimethylammonium 2-acrylamido-2-methylpropanesulfonate were used (Fig. 13).…”

“…23 Several reports suggested that the alternating incorporation of the amine and maleic acid monomers may be attributed to the formation of ions pairs (akin to 13, Scheme 2) in solution and their polymerization. 24,25 In the current work, both the monomers 1 and 2 are fully protonated, and the extent of ionization in a highly concentrated solution (70 : 30 wt ratio of monomer/water) is rather low. This led us to believe that as in the case of the alternating copolymer of styrene and maleic anhydride, the copolymerization described here points towards a preferential combination of electron-rich 1 and electron-poor 2 monomers.…”

“…Allen et al 77 obtained a copolymer of butylacrylate and sulfonated styrene. Salamone et al [78][79][80][81][82] copolymerized styrene, methylmethacrylate, or butyl acrylate with a cationic-anionic monomer pair, 3methacrylamido-propyltrimethylammonium and sulfonated trimethylammonium 2-acryIamide-2methylpropane.…”
