“…The preparation of the electrodes and the experimental procedures have been described (2,10). With respect to our previous studies, the electrodes used in the present work contained a dodecyl sulfate salt of the surfactant ion investigated, solubilized in the electrode membrane.…”

“…We have reported on the interaction between alternated copolymers of maleic acid and alkyl vinyl ethers (referred to as PSX where X is the carbon number of the alkyl chain) and alkyltrimethylammonium halide surfactants (1)(2)(3)(4). The hydrophobicity of these copolymers can be finely tuned by changing the degree of neutralization of the carboxylic groups or the alkyl chain length.…”

“…In this paper we extend these studies to the interaction between some of the above copolymers, the PS1 and PS4 homologues (with methyl and butyl side groups, respectively), and two types of cationic surfactants: the dimeric surfactants polymethylene-α,ω-bis(dodecyldimethylammonium bromide) (CH 2 ) s -α,ω- [C 12 H 25 N + (CH 3 ) 2 ,Br − ] 2 referred to as 12-s-12, with s = 8 and 1 To whom correspondence should be addressed. 16, and the two-chain surfactants dodecyldimethyl(alkyl)ammonium bromides C 12 H 25 (C s/2 H s )N + (CH 3 ) 2 ,Br − ], referred to as 12-s/2, where s/2 is the carbon number of the alkyl chain, with s/2 = 4, 6, 8. The 12-s/2 surfactants can be formally considered as the monomers of the dimeric surfactants 12-s-12.…”

“…Recently, easy to construct and reliable surfactant-sensitive electrodes have become available based on plasticized polymer (for example polyvinyl chloride) (15)(16)(17). This has resulted in studies dealing with the thermodynamics of the binding of cationic surfactants to natural and artificial polymers, colloidal particles, and polyanions (8,10,11). The binding studies led to an understand of the nature of the interaction between surfactants and polymers.…”

The interaction of poly(maleic acid‐co‐alkyl vinyl ether)s and poly(sulfonylethyl maleic acid monoamide‐co‐alkyl vinyl ether)s with and without (cyanobiphenylyl)oxy chromophores with N‐[ω‐(substituted azobenzoxy)alkyl]‐N,N‐dimethyl‐N‐hydroxyethylammonium bromide surfactants has been studied by UV spectroscopy. The azobenzene unit is functionalized at the 4′‐position with a cyano or fluoro substituent and is connected to the surfactant headgroup via a decyl or dodecyl spacer. Upon addition of surfactants to poly(maleic acid‐co‐butyl vinyl ether) the absorption maxima (λmax) of the azobenzene chromophores immediately show their maximum blue shift. This indicates cooperative binding of surfactant to this polymer, and the formation of micelle‐like aggregates surrounded by polyelectrolyte is assumed. Upon addition of the surfactants to the other polyelectrolytes λmax values of the azobenzoxy chromophores gradually shift to lower values indicating a lower cooperativity of surfactant binding. This is attributed to the formation of microdomains by the polyelectrolytes themselves. For these systems the formation of mixed micelles is assumed. The compactness of the microdomains of the maleic acid copolymers is influenced by the pH and binding with surfactants is also influenced by pH. The sulfonylethyl maleic acid monoamide copolymers show no pH dependence in binding above neutral pH. For these polyelectrolytes the cooperativity also becomes less with a longer spacer between backbone and chromophore. Upon elongation of the surfactant spacer or changing the end group from a cyano to the more hydrophobic fluoro substituent a lower λmaxis observed for the chromophores upon initial binding to the polyelectrolytes indicating more cooperative binding. When surfactants and polyelectrolytes are both labelled with chromophores, binding proceeds noncooperatively and the formation of mixed micelles is assumed.
