    摘要: Embodiments of the invention generally relate to polyols having resistance to hydrocarbons and articles made therefrom. More specifically, embodiments of the invention generally relate to hydrophilic polyester-polycarbonate polyols having resistance to hydrocarbons at high temperatures and articles made therefrom. The novel hydrophilic polyester-polycarbonate polyols described herein may be used in adhesive or elastomer applications requiring enhanced oil and/or diesel resistance. The disclosed polyols are liquid at room temperature, which facilitates processing into polyurethane products As described herein, an elastomer made from such hydrophilic polyester-polycarbonate polyols and methylene diphenyl diisocyanate (MDI) retained >90% of tensile strength after 500 hours ageing at 121 degrees Celsius. A comparative example made from a polyester polyol retained 50% of tensile strength under similar conditions.
