Title (EN) URETHANE/UREA-CONTAINING BIS(ALKENYL) ETHERS, PREPOLYMERS PREPARED USING URETHANE/UREA-CONTAINING BIS(ALKENYL) ETHERS, AND USES THEREOF
(FR) BIS(ALCÉNYL)ÉTHERS CONTENANT DE L'URÉTHANE/URÉE, PRÉPOLYMÈRES PRÉPARÉS AU MOYEN DES BIS(ALCÉNYL)ÉTHERS CONTENANT DE L'URÉTHANE/URÉE, ET LEURS UTILISATIONS
Abstract:
(EN) Urethane/urea-containing bis(alkenyl) ethers can be incorporated into the backbone of polythioether prepolymers and can be used as curing agents in thiol-terminated polythioether prepolymer compositions. Cured sealants prepared using compositions containing urethane/urea-containing bis(alkenyl) ether-containing polythioether prepolymers and/or urethane/urea-containing bis(alkenyl) ether curing agents exhibit improved physical properties suitable for use in aerospace sealant applications.
(FR) La présente invention concerne des bis(alcényl)éthers contenant de l'uréthane/urée pouvant être incorporés dans le squelette de prépolymères de polythioéther et pouvant être utilisés comme agents de durcissement dans des compositions de prépolymères de polythioéther à terminaison thiol. Les produits d'étanchéité durcis, préparés à l'aide des compositions contenant des prépolymères de polythioéther contenant un bis(alcényl)éther contenant de l'uréthane/urée et/ou les agents de durcissement à base de bis(alcényl)éther contenant de l'uréthane/urée présentent des propriétés physiques améliorées appropriées pour une utilisation dans des applications d'étanchéité dans le domaine aérospatial.
