Abstract
In this study, waterborne polyurethane was synthesized with polyester polyol, poly(propylene carbonate) (PPC), 4,4-dicyclohexylmethane diisocyanate ($H_{12}MDI$) and dimethylol propionic acid (DMPA) to improve the water resistance. The properties of the synthesized waterborne polyurethane using poly(propylene carbonate) (WPUP) was evaluated through FT-IR, GPC, DSC and UTM. The mechanical properties were increased with the increase in the amount of PPC. When the ratio of polyester polyol to poly(propylene carbonate) is 9:1, the highest water resistance was showed.
