    摘要: A polyester polyurethane compound is formed by reacting trans-1,4-cyclohexanediisocyanate with a mixed polyester. The mixed polyester can be the copolymerization condensation product of an aliphatic dicarboxylic acid or an aromatic dicarboxylic acid, or a separate physical blend thereof reacted with a polyol. The polyurethane can also contain small amounts of non-extractable epoxies and carbodiimides. The urethane has very good hydrolytic stability in comparison with prior art polyurethane systems and also very good fuel resistance and anti-icing resistance. A preferred area of use is an aircraft fuel tanks and anti-icing components.

    摘要: A polyurethane prepared by reacting specifically identified substituted aromatic diamines with isocyanate-terminated prepolymer. Prepolymer is prepared by reacting polyisocyanate with polymeric polyol. Diamines are required to be selected from specified substituted butylbenzoates, benzonitriles or benzoates. The diamine curative is taught to enhance the processing of the prepolymer/diamine mixture for commercial application.
