Abstract
In this study, we have synthesized waterborne polyurethane dispersion(WPU) and analyzed mechanical properties of WPU film and leather coatings in different content of monoammonium phosphate. According to the measured data by DSC, sample WPU-AM3 which included high content of monoammonium phosphate showed the highest Tm at $382^{\circ}C$. All samples had good solvent resistance. In tensile tests, WPU-AM3($2.130kg_f/mm^2$) had the lowest physical properties. Also abrasion resistance properteis and elongation properties were investigated, WPU-AM3 had lowest physical properties with 52.07 mg.loss for abraison and 615 % of elongation.
