In situ polymerisation of monomers in layered double hydroxides

Vinyl or amino-benzene sulfonates (VBS and ABS) are polymerised in situ after a soft thermal treatment (T = 473 K) between the sheets of layered double hydroxides (LDH). The reaction of polymerisation is studied either by ¹³C CP- MAS NMR or ESR spectroscopies. The resonance peak associated to the vinyl group disappears from the VBS/LDH hybrid material, and conversely, a narrow signal, characteristic of free radicals, is observed for the ABS/LDH system.
