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.
Claims28
A composition comprising:
- an olefin-containing system capable of undergoing a metathesis reaction;
- a metathesis catalyst, wherein the catalyst is capable of initiating the metathesis reaction of the composition;
- and
- a silicone-based anionic polymer capable of accelerating the metathesis reaction initiated by the catalyst.
A polymerizable composition comprising:
- a resin system comprising at least one oligomer or polymer functionalized with at least one group curable by ring-opening metathesis polymerization;
- a metathesis catalyst, wherein the catalyst is capable of initiating the ring-opening metathesis polymerization of the composition to form a cured material;
- and
- a silicone-based anionic polymer capable of accelerating the polymerization initiated by the catalyst.
A polymerizable composition comprising:
- a base paste including a resin system comprising at least one oligomer or polymer functionalized with at least one group curable by ring-opening metathesis polymerization, and a silicone-based anionic polymer;
- and
- a catalyst paste including a ruthenium carbene complex catalyst dissolved in a solvent which is miscible with the base paste,
- wherein the catalyst is capable of initiating the ring-opening metathesis polymerization of the composition to form a cured material, and
- wherein the silicone-based anionic polymer is capable of accelerating the polymerization initiated by the catalyst.
