Metathesis Polymers Derived from Plant Oils

Xia, Y.; Lu, Y.; Larock R.C. Ring-opening metathesis polymerization (ROMP) of norbornenyl-functionalized fatty alcohols, Polymer 2010, 51, 53-61. Bio-based polymers are experiencing an explosion of growth, fueled by pressures to move away from traditional petroleum-derived polymer feedstocks. Richard Larock’s group recently published an account of their work with ring-opening metathesis polymerization (ROMP) of vegetable oil-derived […]

Lowdown on Catalyst Loadings in Ru-catalyzed Metathesis Reactions

When reviewing the scientific literature related to ruthenium-catalyzed olefin metathesis, it is common place to observe the use of relatively high catalyst loadings. Typically, catalyst loadings employed are in the range of 1-5 mol% or greater depending on the specific application. An immediate question arises: Are these types of catalyst loadings required…or is it a […]
