Formation of Hydrotalcite–Acrylate Intercalation Compounds and Their Heat-Treated Products

Abstract Hydrotalcite-like compounds (HT), layered double hydroxides with a few kinds of interlayer anions (X=CO32−, Cl−, and NO3−) were allowed to react with acrylate anions in order to prepare a novel inorganic–organic interstratified layered material by anion exchange. When HT–CO3 was used the anion exchange reaction did not occur. When HT–NO3 was employed the reaction proceeded to form a HT–acrylate intercalation compound. The formation of the intercalation compound from HT–Cl was observed only under a reaction condition using a concentrated acrylate solution. When the intercalation compound was heated at 80 °C with the addition of an initiator, the interlayer acrylate anions were polymerized to form a HT–polyacrylate intercalation compound.
