Synthesis and Characterization of Modified Polyamide-Amine Anionic Dendrimers
摘要
Abstract
The modified polyamide-amine ( PAMAM) anionic dendrimers were synthesized by grafting sodium acrylate ( SAA) or 2-acrylamide-2-methyl propyl sulfonic acid ( AMPS) as terminal group anionic modifier onto the fourth-generation polyamide-amine (PAMAM G4. 0) dendrimer core through Michael addition reaction. The optimum reaction conditions were: methanol as the solvent, mole ratio of PAMAM G4.0 to SAA or AMPS 1 : 192, reaction time 96 h and reaction temperature 50 ℃. The modified dendrimers were characterized by means of FTIR, NMR and GPC to determine their structures and relative molecular masses. The results showed that the synthesized products were the modified PAMAM anionic dendrimers. The ionization degree of the product polymers could reach more than 90% and had good monodispersity.关键词
