Abstract
The anionic waterborne polyurethane emulsion was synthesized with the chemicals such as is ophoronediisocyanate (IPDI), polycarbonatediol (PCDL-1000), polyethylene-1, 4buthylenea dipateglycol (PBA-2000), dimethylol propionic acid (DMPA) and 2-hydroxyethylacrylate (HEA). The effect of the mole ratio of (PBA/PCDL) on the mechanical properties of the waterborne polyurethane (WPU) dispersion was studied. The chemical structure of emulsion particle was determined by Fourier transform infrared spectroscopy (FT-IR). Some properties were measured such as the particle size of the emulsion, the elongation at break, tensile strength and thermal stability of the film. The results indicated that when increasing the mole ratio of (PBA/PCDL), the tensile strength and thermal stability of the film was improved, the elongation at break was the contrary, and the particle size of the emulsion was increased. The films showed improvement in the thermal stability and mechanical properties when increasing the molecular weight of the polyol due to the increase in the formation of strong interaction between the hard segment and soft segment. The vinyl group on the WPU provides a crosslink site when the polymerization between the WPU and the acrylate.
