Abstract
A polymerizable composition including a resin system comprising oligomers or polymers functionalized with groups curable by ring opening metathesis polymerization, a metathesis catalyst, and a catalyst accelerator. In examples of the present invention, the composition includes a ruthenium carbene complex catalyst capable of initiating ring-opening metathesis polymerization of the composition and a silicone-based sulfosuccinate salt capable of accelerating the polymerization initiated by the catalyst. In another example, the invention includes a paste/paste system in which a base paste includes the polymerizable oligomer or polymer and the catalyst accelerator and in which a catalyst paste includes the catalyst dissolved in an inert solvent.
