    摘要: The present invention provides polyurethane foams and elastomers made with an alkoxylated vegetable oil hydroxylate replacing at least a portion of the typically used petroleum-based polyol(s). Also provided are processes for making the inventive foams and elastomers and for making alkoxylated vegetable oil hydroxylates. The alkoxylated vegetable oil hydroxylates are environ mentally-friendly, bio-based polyols which advantageously also offer the potential of improved hydrophobicity in polyurethane foams and elastomers. The inventive polyurethane foams and elastomers may find use in a wide variety of products such as automobile interior parts, polyurethane structural foams, floor coatings and athletic running tracks.

    摘要: 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.
