“…Additionally, a non-homogeneous distribution of the initiator in the different domains (hydrophobic or hydrophilic) could occur, leading to a modification of the expected characteristics of the polymer. It has been previously reported that X-rays act as an initiator in the polymerization of acrylamides, acrylates, or ethylene glycol . Besides, the high photon flux of synchrotron radiation provides a method to follow the polymerization process in situ, by the change in the scattering curves, from the initial mixture to the postpolymerized state .…”

The influence of the monomer diallyldimethylammonium chloride (D) on the lamellar liquid crystal formed by the anionic surfactant aerosol OT (AOT) and water is investigated, determining the lamellar spacings by SAXS and the quadrupolar splittings by deuterium NMR, as a function of the D or AOT concentrations. The cationic monomer D induces a destabilization of the AOT lamellar structure such that, at a critical concentration higher than 5 wt %, macroscopic phase separation takes place. When the monomer, which is dissolved in the AOT lamellae, is polymerized in situ by X-ray initiation, a new collapsed lamellar phase appears, corresponding to the complexation of the surfactant with the resulting polymer. A theoretical model is employed to analyze the variation of the interactions between the AOT bilayers and the stability of the lamellar structure.
