Abstract
This paper describes for the first time the combination of a polymerizable surfactant, sodium 2-acrylamido-dodecane sulfonate (NaAMC12S), and a hydrophobic monomer to prepare water-soluble associating polymer via a new micellar process. In this method, the hydrophobic monomer, N-dodecylacrylamide (C12AM) or N,N-didodecylacrylamide (DiC12AM), was first solubilized within NaAMC12S micelles, whereas the hydrophilic monomer acrylamide (AM) was dissolved in the aqueous continuous medium. The micellar copolymerization, therefore, resulted in a ternary hydrophobic association polyacrylamide (HAPAM), namely, C12AM/NaAMC12S/AM or DiC12AM/ NaAMC12S/AM. The chemical structures of these ternary copolymers were characterized with Fourier transform infrared (FTIR) spectroscopy, and their hydrophobic associative behavior as well as the relationship between microstructure and hydrophobic associative property was studied by a combination of the fluorescence probe technique and viscosimetry. The experimental result shows, ...
