  Abstract

Various waterborne polyurethanes (WPU) with three different types of polyol such as ester type polyol [adipic acid (A)/BD/3-methyl-1,5-pentandiol (MPD) and A/BD]//carbonate type polyol (C/HD/MPD, C/HD, C/BD)//ether type polyol (PTMG) were prepared in this study. This study focused on the effect of polyol type on the properties of WPU. Soft segment Tg (Tgs), 100% elastic modulus and tensile strength were highest when using carbonate polyol, followed by ester polyol and ether polyol, while those of elongation showed the opposite trend. The WPU synthesized with MPD - containing polyol showed lower Tgs, 100% elasticity and strength, and higher elongation than MPD - free WPU. The % transmittance and transparency of the WPU film containing the MPD component was superior to that of the WPU film containing no MPD component, and it was found that the film based on carbonate polyol was slightly better than the film based on ester polyol and ether polyol.
