The copolymerization system of acrylamide (AM) and styrene (St) was acquired by using amphiphilic block copolymer PAM-b-PSt with lower molecular weight as polymeric surfactant, and then the microemulsion phase diagram was drawn. The appropriate copolymerization systems were chosen in the phase diagram, and higher molecular weight amphiphilic block copolymers PAM-b-PSt were prepared by self-emulsifying microemulsion method. The chemical composition and structure of the products were analyzed by FTIR, 1 H-NMR, 13 C-NMR, GPC, and UV; the block structure of products was characterized by DSC, and the hydrophobic association property of the products was studied by the fluorescence probe and rotating viscosity measurement. The results showed that O/W microemulsion was also acquired by using the polymeric surfactant; 3 g polymeric surfactant was only used to disperse 0.25 g St into aqueous solution, which showed higher emulsifying efficiency. At the same time, the use of self-emulsifying microemulsion copolymerizing system can avoid back treatment of small molecular surfactant and the purified block polymer was prepared in one step; the prepared copolymers have good hydrophobic association properties and their aqueous solution showed evident viscosity increment.

“…As far as to we know, the preparation of PAM-b-PSt by this method was not reported. Compared with micelle method 13 and general microemulsion method, 9 the method cannot only avoid the complicate purified back treatment of surfactant, but can also make the efficiency of block copolymerization higher.…”

“…The copolymers of AM, AMPS, and BAAM [poly(Narylalkylacrylamide-co-acrylamide-co-2-acrylamide-2-methylpropanesulfate) (PBAMS)] were prepared by micellar copolymerization 18,19 with sodium dodecyl sulfate (SDS) as the surfactant and ammonium persulfate/sodium bisulfite as the redox free-radical initiator. Each reaction was conducted in a 100-mL, threenecked, round flask equipped with a mechanical stirrer and nitrogen inlet and outlet.…”

“…18,[23][24][25] Phenyl groups are well known to induce van der Waals interactions because of their planar and polarizable structure, and so the incorporation of an aromatic group into hydrophobic groups can stabilize the hydrophobic associations involved with alkyl chains. Furthermore, phenyl groups can act as spacers, increasing the rigidity of the structure.…”

Copolymers of acrylamide, 2-acrylamide-2-methylpropanesulfate (AMPS), and hydrophobic monomer N-arylalkylacrylamide (BAAM) were synthesized by freeradical micellar copolymerization. The effects of the copolymer, BAAM, AMPS, and NaCl concentrations and the pH value on the apparent viscosity of the copolymers were studied. The solution viscosities increased sharply when the copolymer concentration was higher than the critical associating concentration. The apparent viscosities of aqueous solutions of poly(N-arylalkylacrylamide-co-acrylamide-co-2-acrylamide-2-methylpropanesulfate) (PBAMS) increased with increasing BAAM and AMPS concentrations. PBAMS exhibited good salt resistance. With increasing pH, the apparent viscosities first increased and then decreased. Dilute PBAMS solutions exhibited Newtonian behavior, whereas semidilute aqueous and salt solutions exhibited shear-thickening behavior at a lower shear rate and pseudoplastic behavior at a higher rate. Upon the removal of shear, the aqueous solution viscosities recovered and became even greater than the original viscosity, but the salt solution viscosities could not recover instantaneously. The elastic properties of PBAMS solutions were more dominant than the viscous properties, and this suggested a significant buildup of a network structure.

“…Micelles can concentrate the reactants within their small volumes (1)(2)(3)(4); stabilize substrates, intermediates, or products (5,6); and orient substrates (7)(8)(9) so that ionization potential and oxidation-reduction properties, dissociation constants, physical properties, quantum efficiencies, and reactivity are changed (10)(11)(12). Thus micelles can also alter the reaction rate, mechanism (13), and regio-and stereochemistry (14,15).…”
