Abstract
Abstract Eight novel polymerizable monovalent quaternary ammonium bromide surfactants and five model non-polymerizable structurally analogous surfactants have been synthesized. Methylation of free amine groups in six of the polymerizable monoquaternary ammonium species has yielded the corresponding divalent diquaternary ammonium dibromide surfactants, and likewise, five non-polymerizable divalent diquaternary ammonium dibromides have been prepared. All the new molecules have been characterized structurally by elemental microanalysis and 1 H nuclear magnetic resonance spectroscopy. The solubility, melting behaviour and homopolymerizability of the monomers have been evaluated and the results discussed with those of structurally related systems already in the literature.
