11-acryloyloxyundecyltrimethylammonium bromide

It was also shown that the core materials influence the conductivity of the composite particles. Nano-sized PS-PPy composites have been reported by Xu et aL [72], who also noted that when the cationic, nonpolymerizable surfactant cetyl-triemethylammonium bromide (CTAB) was used as stabilizer, the latex particles prepared showed poor colloidal stability and low electrical conductivity (Fig. 6.13) compared to that of latexes stabiHzed by nonionic polymerizable surfactant (o-methoxy[poly(ethylene oxide)4Q] undecyl a-methacrylate (PEO-R-MA-40) and cationic polymerizable surfactant (o-acryloyloxyundecyltrimethylammonium bromide (AUTMAB). These authors also proposed that the poor colloidal stability and low conductivity of the composite particles were due to the desorption of CTAB...
