| Résumé : |
A series of hyperbranched polymer surfactants (HBP-C8, HBP-C12 and HBP-C16) were synthesized by the reaction between hydroxyl-terminated hyperbranched polymers (HBP) and fatty acyl chloride. The structure of obtained hyperbranched polymer surfactant was characterized by FTIR, NMR and GPC. The results showed that the products have amphiphilic structure. The thermal property of the hyperbranched polymer surfactant investigated by DSC and TGA was strongly influenced by the length of end alkyl chain. Surface activity of hyperbranched polymer surfactant was analyzed by surface tension method and UV spectrophotometry, respectively. The results showed that hyperbranched polymer surfactant took on better surface activity, which can effectively reduce the surface tension of the water. The hyperbranched polymer surfactant has a lower critical micelle concentration (CMC) and displays single molecular micellar properties, which can package small hydrophilic molecules in relatively low concentration. |
