高纯度树状大分子聚酰胺-胺的合成与表征
Synthesis and Characterization of High Purity Polyamidoamine Dendrimers
摘要
Abstract
n0. 5G ~ 5. 0G dendrimers with ethylene diamine as core were synthesized from alternating eopolymeraziation of methacrylate by Michael addition reaction. The structures of all products were characterized by FTIR, 1H NMR, HPLC, and elemental analysis- The influences of the reaction temperature, reaction time and ratio of reactants were investigated. The reaction temperature is 25 ℃ for the half-generations and 35 ℃ for the full-generations. The optimum reaction time is 18 h, for 0. 5G, 24 h for 1. 0G and 1.5G, 36 h for 2. 0G and 2. 5G, 48 h for 3. 0G and 3. 5G, 3 d for 4. 0 and 4.5G, and 4 d for 5. 0G. The main difficulty in the synthesis is the separation and purification of the products. The results showed that the purity of polyamidoamine dendrimers was improved by solvent extraction using ether as. exteactant and etkanol as exchanged solvent.关键词
