Poly(vinyl sulphonate) (PVS) was intercalated into a carbonate-layered double hydroxide (LDH-CO3), after an intercalative reaction with stearic acid in a novel one-pot reaction. The intercalated stearate ion exchanged with the PVS to form sodium stearate and LDH-PVS. Within an hour at 78 degrees C, all the carbonate anions reacted. The PVS intercalated material had low crystallinity and featured an interlayer distance of 13.91 angstrom attributed by Oriakhi et al.(1) to a bilayer intercalation. If this intercalative reaction were to be conducted during the emulsion polymerization of other polymers, the intercalated LDH could be well dispersed, leading to nanocomposite formation.
