제목 Ethylene oxide functionalized vegetable oil based polyol for waterborne polyurethane dispersion
초록 Due to growing concerns on environmental issues and volatile organic compounds, waterborne polyurethanes (WPUs) have drawn attentions in polymer industry. Ethylene oxide (EO) has been widely used as soft segment for the WPUs because of its hydrophilic nature. In this study, preparation of hyperbranched polyols with EO functionalities were attempted through thiol-ene click reaction between soybean oil (SO) and thiol-containing EO compounds. The resulting SO-based polyols were successfully incorporated into WPUs, exhibiting hyperbranched chain architectures. Proton nuclear magnetic resonance spectroscopy and gel permeation chromatography were employed to investigate the functionalities and structural characteristics of the EO-functionalized SO-based polyols and WPUs. Thermal and mechanical properties of the WPUs were evaluated, along with their dispersion stability behaviors.
