Abstract: Provided are ultraviolet (UV)-curable polyols and polyurethane compositions made by reacting the inventive polyol with an isocyanate. The inventive ultraviolet (UV)-curable polyol is made by co-polymerizing an alkylene oxide, an unsaturated carboxylic acid or anhydride and a hydroxy functional compound in the presence of a double metal cyamide (DMC) complex catalyst such that the polyol has an ultra-low level of unsaturation. The inventive polyols may be used to produce prepolymers, which in turn may be useful in making thin films which in turn may provide such items as medical examination gloves and scientific gloves. The inventive ultraviolet (UV)-curable polyurethane compositions may also find use in or as coatings, adhesives, sealants, elastomers and the like.

Abstract translation: 提供紫外线（UV）可固化的多元醇和通过使本发明多元醇与异氰酸酯反应制备的聚氨酯组合物。 本发明的紫外线（UV）可固化多元醇是通过在双金属环酰胺（DMC）配合物催化剂的存在下使烯化氧，不饱和羧酸或酸酐与羟基官能化合物共聚而制得的，使得多元醇具有超 低于不饱和度。 本发明的多元醇可以用于制备预聚物，其又可用于制备薄膜，其又可以提供诸如医疗检查手套和科学手套的物品。 本发明的紫外线（UV）可固化聚氨酯组合物也可用于或作为涂料，粘合剂，密封剂，弹性体等。
