dc.description.abstractEnA series of crosslinkable waterborne polyurethanes (WPU) from bio-sourced diol were synthesized by the acetone process. WPU raise much interest in coating and adhesives application due to its low volatile organic compounds emission. Crosslinking of the obtained PU film should improve mechanical properties and water and solvent resistance. In this study, N-methyldiethanolamine (MDEA), the emulsifier, was used as short hydrophilic diol to obtain a cationic dispersion after quaternization with acetic acid. The crosslinker, N-4-vinylbenzyl-diethanolamine (VBDEA) synthesized in this study, also contains a tertiary amine which can improve dispersion in addition to the mechanical properties. Finally, a telechelic diol (Priplast 1900) obtained by polyesterification of dimer fatty acid was used as long hydrophobic diol. Stable PU water dispersions (40 wt%) were obtained by acetone process with various diisocyanates 'HMDI, HDI and IPDI) and characterized by DLS. After complete evaporation of water, films were obtained from these dispersions. Then, the films were crosslinked by solar irradiation. The network formation was confirmed using swelling test in acetone and THF. Films were compared after and before irradiation demonstrated that irradiation improves solvent and water resistance but also mechanical properties of each film.
