“…Therefore, simple modification in the experimental method of micelle preparation may be used to alter the shape of the micelles. As per Tian and his group, the micelle properties are very stable once the micelle resides in a solvent that is a strong nonsolvent for the core [110].…”

A fluorescence experiment involving mixing donor-labeled micelles with acceptor-labeled unimers has been designed and a kinetic scheme for describing such an experiment has been proposed. An approximate analytical solution was found for the decrease in the donor fluorescence intensity at time t after sample mixing relative to that at time zero, I(t) [I(O). Treating the data of this decrease in donor fluorescence intensity as a function of time using the derived equation allows the simultaneous determination of the rate constant k,, for unimer incorporation into micelles and the quenching efficiency cp of donor fluorescence by an acceptor in a micelle.Key words: polymer micelles, dynamics, chain exchange, energy transfer.RCsumC : On a mis au point une expCrience de fluorescence impliquant le melange des micelles contenant un donneur marquC avec des unimkres accepteurs marquCs et on propose un schCma cinCtique pour dCcrire une telle expkrience.

“…Poly(sodium methacrylate) (PNaMA), a water-soluble polyelectrolyte, has been used for many objectives, such as surface modification of the wettability and friction [1], suppression of cell adhesion and protein adsorption [1,2], and self-assembly studies on amphiphilic block copolymers in aqueous media [3][4][5][6][7]. While PNaMA and its copolymers were prepared through the living anionic or living radical polymerizations of methacrylates with protecting groups of tert-butyl and benzyl, followed by deprotection [3][4][5][6][7], those were also directly obtained by the controlled/living radical polymerization of sodium methacrylate (NaMA) in water.…”

For instance, the atom transfer radical polymerization (ATRP) of NaMA produced PNaMA with a well-controlled molecular weight [8].…”

The aqueous photo-living radical polymerization of sodium methacrylate (NaMA) was attained using 2,2 -azobis{2-methyl-N-[1,1-bis(hydroxymethyl)-2-hydroxyethyl]-propionamide} (V-80) as the initiator and 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (HTEMPO) as the mediator in the presence of (4-fluorophenyl)diphenylsulfonium triflate (FS). The polymerization was carried out in water at room temperature by irradiation using a high-pressure mercury lamp. Whereas the polymerization by V-80 and/or FS in the absence of HTEMPO produced polymers with very high molecular weights and broad molecular weight distributions, the HTEMPO-mediated polymerization provided still lower-molecular-weight distributions using both V-80 and FS. The first-order time-conversion plots had an induction period up to 2.5 h; however, they thereafter showed a linear increase. The conversion-molecular weight plots also exhibited a linear correlation. A linear correlation was also obtained for the plots of the molecular weights versus the reciprocal of the initiator concentration. Based on these three correlations, it was found that the HTEMPO-mediated photopolymerization proceeded by a living mechanism.
