| Résumé : |
Using hydroxyl terminated hyperbranched polymer as the core, dimethylol propionic acid (DMPA), dimethylolbutanoic acid (DMBA), carboxylic acid type monomer (DMCA) as the hydrophilic chain extenders respectively, three different types of hyperbranched waterborne polyurethane leather finishing agents were synthesized. The structures and properties of the products were characterized by FT-IR, SEM, AFM and TG. Simultaneously, the mechanical properties, surface wettability and water and solvent resistance of three films were studied. The results found the order of crystallinity to be : DMBA-HWPU |
