Research entitled "Synthesis and characterization of poly(ethylene glycol) bottlebrush networks via ring-opening metathesis polymerization" was recently published in the Journal of Polymer Science by Brandon R. Clarke* and Gregory N. Tew*. Discrete PEG bottlebrush polymers and PEG bottlebrush networks are synthesized from PEG with difunctional impurities using the overlap concentration (C*) as a guide.
