The first and second generation multiacrylic dendrimers were obtained in good yields following the strategy proposed by Newkome et al. based on the reaction between pentaerythritol and acrylonitrile. Both compounds were thermally polymerized in solution and in bulk through a radical addition reaction. The soluble products were characterized by IR, H-1 and C-13-MNR spectroscopies and GPC. The crosslinking products were studied by IR, swelling indexes, DSC and TGA. Second generation monomers produced highly crosslinked materials, more compact and less-swellable than those obtained from the first generation monomer. These dendritic monomers showed typical behavior previously described in macromonomers chemistry.
