Document Type and Number:
Japanese Patent JP6657414
Kind Code:
B2
Abstract:
Reactive antioxidants, antioxidant-containing prepolymers, compositions containing reactive antioxidants and antioxidant-containing prepolymers, methods of synthesizing reactive antioxidants and reactive antioxidant-containing prepolymers and the use of reactive antioxidants and antioxidant-containing prepolymers in aerospace sealant applications are disclosed. Reactive antioxidants and antioxidant-containing prepolymers can be added to a curable composition and react with a curing agent to become incorporated into the cured polymer network. Antioxidant-containing prepolymers have antioxidants incorporated into the backbone of the prepolymer. Cured sealant compositions comprising reactive antioxidants and antioxidant-containing prepolymers exhibit enhanced thermal resistance.
