제목 | Synthesis and Characterization of Multifunctional Dendritic Macromolecules by A2+B3 Polymerization |
초록 | Hyperbranched polymers have gained more attention due to the availability of these materials by one-pot synthesis. and their interesting properties such as low viscosity and good solubility. In this study we synthesized carboxylic acid containing poly(arylene ether ketone) from the carboxlyic acid containing monomer by direct A2+B3 Polymerization, because postfunctionalization of polymers is often difficult to control. 3,5-Dihydroxy-benzoic acid (A2 monomer) and 1,3,5-tris(4-fluorobenzoyl)benzene (B3 monomer) were condensed through nucleophilic aromatic substitution reaction. The multifunctional hyperbranched polymer with both the fluorine end groups and the carboxylic acid groups in the internal backbone are expected to have potential applications in many areas. |
