Several dendrimer–clay nanocomposites have been prepared. Firstly, the dendrimer (DE1)/clay nanocomposite was obtained via an in situ free radical polymerization of a double bond-ended dendrimer (DE1), derived from Behera's amine by using 2,2′-azobisisobutyronitrile (AIBN), as initiator, and Cloisite 30 B, as nanofiller. Further free radical in situ copolymerization processes were conducted between DE1, methyl methacrylate (MMA), and styrene (St). Two other dendrimer/clay nanocomposites were prepared by the reaction of second generation (G2)–36-acid dendrimer (DE2) and N,N′,N′,N′-tetrakis[2-hydroxy-1,1-bis(hydroxylmethyl) ethyl]-α,α,ω,ω-alkane-tetracarboxamide [6]-10-[6] Arborols (DE3) with montmorillonite clay (MMT).
