BACKGROUND: Following our recent synthesis and characterization of three new families of cationic amphiphilic polymers with great structural variability, this paper reports their physical chemical properties in aqueous media in relation to their chem

In order to offer new tools for developing structure–property relationships for intramolecular associative polymers (polysoaps), the synthesis of three families of comb-like amphiphilic cationic polymers with great structure variability is describe

The micellization and adsorption of two short chain perfluorodiols 3,3,4,4,5,5,6,6,6-nonafluorohexane-1,2-diol (nFHD) and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctane-1,2-diol (tFOD) are examined from a thermodynamic point of view as a function of t

Solvents can strongly influence the equilibrium between dormant and active species which is involved in 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-mediated radical polymerizations. At 110°C, the overall polymerization rate of 3-vinylpyridine in py

Fluorescence spectroscopy based on pyrene and DMAC (i.e., 1,1-dicyano-4-(4′-(N,N-dimethylamino)phenyl)-1,3-butadiene) probes was used to investigate the aggregation of amphiphilic polymers in aqueous solution. The fluorescence data related to the c

The influence of nitroxide concentration, solvent, and temperature on the nitroxide-mediated radical polymerization of 3-vinylpyridine (3VP) was examined. Long-chain poly(3-vinylpyridine)s with low polydispersities were synthesized. The initial 2,2,6

Random copolymers of 3-hexadecyl-1-vinylimidazolium bromide and N-vinyl-2-pyrrolidinone were synthesized by free radical copolymerization at various feed compositions. These copolymers, whose structure was determined by 13 C NMR spectrometry, self-ag

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 aqueous solution properties and the micellar structure of two short-chain nonionic surfactants containing a hydrocarbon tail, 1,2-hexanediol (HD), and a perfluorinated tail, 3,3,4,4,5,5,6,6,6-nonafluoro-1,2-hexanediol (PFHD), have been compared b
