| Abstract: | Our preliminary results towards the synthesis of hyperbranched polyamidoamine (PAMAM) polymers as ‘dendrimer equivalents’ is described. An aromatic AB2 bis-amino acid monomer was polymerised at 165 °C (under vacuum) and the crude mixture purified by dialysis. Analysis by GPC and MALDI-TOF mass spectroscopy showed that the purified hyperbranched polymers possessed an Mn of 2000 and a PD of 3.2. |
