N2 - 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. In this respect, the new bifunctional surfmers were prepared by reacting polyoxyethylene 4-nonyl -2-propylene-phenol nonionic reactive surfactant with maleic anhydride followed by esterification with poly (ethylene) glycol. The polymerizable surfactant has high surface activity used to prepare crosslinked N-isopropylacrylamide (NIP Am) and 2-Acrylamido-2-methylpropane sulfonic acid (AMPS) copolymer nanoogel based on nonaqueous emulsion copolymerization. The morphology 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.
