Several dendrimer–clay nanocomposites have been prepared. Firstly, the dendrimer (DE 1 )/clay nanocomposite was obtained via an in situ free radical polymerization of a double bond‐ended dendrimer (DE 1 ), derived from Behera's amine by using 2,2′‐azo bis isobutyronitrile (AIBN), as initiator, and Cloisite 30 B, as nanofiller. Further free radical in situ copolymerization processes were conducted between DE 1 , methyl methacrylate (MMA), and styrene (St). Two other dendrimer/clay nanocomposites were prepared by the reaction of second generation (G 2 )–36‐acid dendrimer (DE 2 ) and N , N ′, N ′, N ′‐tetra kis [2‐hydroxy‐1,1‐ bis (hydroxylmethyl) ethyl]‐α,α,ω,ω‐alkane‐tetracarboxamide [6]‐10‐[6] Arborols (DE 3 ) with montmorillonite clay (MMT).
