Abstract

Polyurethane curable systems that contain an aminated glycerol as a catalyst to enhance the cure rate of the systems. The systems are based on polyoxyalkylene polyols that can be either polyether or polyester polyols. In addition, the polyols can be those that are provided by natural oils, such as soybean, corn oils, and the like. The polyols are typically dihydroxy functional, but can be tri- or quadra-functional or more. The systems are comprised of the reaction of such polyols with organic isocyanates, including the use of chain extenders from diols, or a mixture of triols and diols, such that the overall functionality of the mixture is generally less than 2.3. The organic isocyanates are also at least di-functional and can be tri- or greater functional, with regard to the isocyanate groups used on such molecules. The polyurethane systems can be, for example, elastomers, sealants, adhesives, or foamable systems.
