Rigid aromatic fractal polyamides
Authors:Shaul M Aharoni
Abstract:The preparation of rigid aromatic, highly branched polyamides is described. Owing to the method of preparation and the chosen ratio of difunctional to trifunctional monomers, these entities are highly porous and not dendrimeric in nature. They better conform with the fractal model and are therefore called fractal polyamides (FPs). The effects of variations in the polymerization procedure, in total monomer concentration, in the ratio of amine to carboxyl groups and in the duration of the polycondensation reaction are investigated. Some characterization was performed and the results are presented and briefly discussed.
Keywords:aromatic polyamides  fractal polymers  porous structure  synthesis of rigid polymers  dendrimers  photon correlation spectrometry  viscosity  WAXD
