    摘要: Provided herein are polymers, including polyureas, polyurethanes, and polyurea-polyurethane hybrids, made from an isocyanate, a secondary polyetheramine, an aspartic ester amine, and optionally a polyol. The secondary polyetheramine may be used in combination with the aspartic ester amine to increase flexibility or modify other properties and lower cost of the final polymer product while maintaining a desirable cure time.

    摘要: Disclosed are derivatives of isophorone diamine exhibiting a synergistic relationship with other commonly employed chain extenders offerings enhanced efficacy with regard to slowing of the polyurea elastomer cure profile, and processes employing their use. According to the invention, extensions of the gel-free and tack-free times are more readily achieved at lower loading levels for these chain extender blends than are afforded through the sole use of the individual molecules.
