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.

摘要： Disclosed are hydrophobic polyester-polycarbonate polyols which are the reaction product of (a) a polyester polyol and (b) one or more polycarbonate polyols. The polyester polyol (a) is the reaction product of: (i) one or more hydrophobic monomers, (ii) one or more organic acids, and (iii) one or more alcohols having an OH functionality of 2 or more. The polyester-polycarbonate polyols may be both amorphous and liquid at room temperature and have excellent hydrolytic stability. The hydrolytic and chemical performance of the polyester-polycarbonate polyols described herein is superior to that of commercially available hydrophobically modified polyester polyols and to that of commercially available polyester-polycarbonate polyols as described herein.
