Abstract
Styrene and the cationic surfactant 11-(acryloyloxy)undecyl(trimethyl) ammonium bromide (AUTMAB) form transparent, globular microemulsions in water without any addition of a cosurfactant. Upon gamma-irradiation, the two monomers copolymerize at room temperature and form nanolatex particles of about 21 nm in diameter consisting of a copolymer with a mole ratio of styrene to surfactant of approximately 1.5:1. Excess sur factant is polymerized in the micellar solution by formation of homopo lymer. A structure model is presented taking into account that the sur factant most likely forms the particle shell. Due to the polar, covale ntly bonded shell the polymer particles can be easily redispersed.
