The esterolytic activity of metal ion complexes of n -alkyl-2-hydroxymethylbenzimidazoles/Zn 2+ towards p -nitrophenyl esters (picolinates and alkanoates) was investigated in the presence of an amphiphilic polymer, poly(1-hexadecyl-3-vinylpyridinium

The behaviour in aqueous medium of cationic amphiphilic copolymers derived from 3-vinylpyridine has been studied. The ability of these polymers to form hydrophobic microdomains was shown by fluorescence spectroscopy using a molecular rotor as a fluor

The behaviour of new cationic amphiphilic copolymers derived from 3-vinylpyridine was studied in aqueous medium. The formation of hydrophobic microdomains was evidenced by fluorescence spectroscopy using a molecular rotor as a fluorescent probe and t

The purpose of the present investigation deals with a comparative study between the magnitudes of the local viscosity and/or the polarity of the hydrophobic microdomains generated by poly (3-hexadecyl-1-vinylimidazolium bromide) in an aqueous medium

Cationic amphiphilic polymers (e.g. polyvinylpyridinium bromides and polyvinylimidazolium bromides) adopt a compact coiled form in aqueous solutions. In the case of former polymers, the resulting hydrophobic microdomains are evidenced only by fluores

Homopolymers and random copolymers derived from 3-vinylpyridium salts form compact coils in aqueous solutions. The resulting hydrophobic microdomains were characterized by both the hypsochromic shift of the wavelength emission band and the fluorescen

We report on the preparation and the characterization of R-alkylated quaternary salts (with RCCH3, C12H25, C16H33, X=Br-) derived from 3-vinylpyridine (3-VP). Our first attempts on free radical polymerization of 1-hexadecyl-3-vinylpyridinium bromide
