Abstract

Certain room temperature ionic liquids (RTILs) are utilized to initiate cure or as additives to manage mechanical properties in thermosetting epoxy resins. Curing thermosetting epoxy resins in the presence of room temperature ionic liquids which may initiate curing and/or act as additives to manage mechanical properties of the thermosetting epoxy resins is disclosed, as well as ionic liquids useful for curing thermosetting epoxy resins and/or to act as additives to manage mechanical properties of the thermosetting epoxy resins. The ionic liquids may form part of a curing accelerator. Resin compositions comprising a compound which contains an epoxy group and at least one ionic liquid are also disclosed, as are cured products obtained by curing a resin composition in accordance with the present invention. Tunable properties of the epoxy resins of the present invention include ability to vary cross-linker ratios, the ability to vary non-reactive RTIL concentration possessing desired characteristics.
