The improved latency makes it possible to make the solution of ruthenium in monomer far ahead of molding and curing, rather than immediately before use. A. Muhlebach, P. A. van der Schaaf, and A. Hafner used ruthenium carbene catalysts, combined with non-carbene ruthenium catalysts, to increase the activity and latency of the ROMP system. Each polymerization was run neat, by dissolving the catalysts in DCPD and then degassing. How that happens is a puzzle. There's something interesting going on here, but the authors don't even speculate about the mechanism.
Metals play an important role in the dyeing of textiles.
Generally, the metals form covalent or ionic interactions between the fabric and the dye. Once the dye is anchored, the color imparted to the fabric is colorfast unless the coloring agent is degraded by photo- or chemical bleaching. Protective coatings are often used to accomplish colorfastness. When metal particles are finely divided, very distinct colors are obtained, depending on the metal, the particle size, and particle concentration. Controlling particle aggregation can greatly influence the final color.
