In chemistry, a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Catalysts work by providing an alternative pathway for the reaction to occur that requires less energy, which lowers the activation energy required for the reaction to proc...

Our resin formulations are based on cyclic C5 monomers and other proprietary monomers and additives. Our catalyst formulations have strong foundations in Nobel Prize-winning technology developed by Professor Robert Grubbs and his research team. This powerful combination produces polymers that can outperform...

Cyclopolymerization of 1,7-octadiynes using a ruthenium-based Grubbs catalyst, to produce conjugated polymers containing six-membered rings as repeat units is generally much slower than the corresponding polymerization of 1,6-heptadiynes, and thus it is considered less useful. Here, we demonstrate ...
Exemplary is the enhanced activity of the second-generation Grubbs metathesis catalyst [(Cy_3P)(L)Cl_2Ru=CHPh] [L = 1,3-dimesityl-4,5-dihy-droimidazol-2-ylidene (H_2IMes)] relative to that of the first-generation catalyst (L = Cy_3P), which is caused by the differences in 蟽-...
