Synthesis and Surface Activity of Amphiphilic 2-Acylamido-2-Methylpropane Sulfonic Acid – co-N-Isopropyl Acylamide Nanoparticles in Non-Aqueous Media


Keywords: , , , , ,

In this work, we synthesized a series of nonionic polymerizable nonyl phenol ethoxylates (NPEs) as organic solvent-soluble surfactants in which straight, branched and cyclic alkyls and phenyl acted as solvophilic segment and polyoxyethylene, or maleate chains as solvophobic segment. The chemical structure of the prepared surfactants was determined by 13 C and 1H NMR analyses. The polymerizable surfactant has high surface activity used to prepare crosslinked N-isopropylacrylamide (NIPAAm) and 2-Acrylamido-2-methylpropane sulfonic acid (AMPS) copolymer nanoogel based on nonaqueous emulsion copolymerization. The morphology and thermal characteristics of the NIPAAm/AMPS nanogels were characterized and indicated that well dispersed nanoparticles were prepared and used as stabilizer for nonaqueous polymerization of styrene and AMPS monomers.
