Recently, Cheng and coworkers reported the synthesis of brush-like polymers, by which the main polymer chain was prepared using ROMP followed by polymerization of peptide units on the amine side chain with N-carboxyanhydrides. These new materials may extend the application of brush-like polymers to include new ranges of properties. In this report, the authors use the Grubbs catalyst (3rd Generation) to polymerize the norbornene monomers. Excellent polydispersity of the polymer was reported with PDI ranges of 1.03 to 1.15 (Scheme 1).1
