Abstract
AbstractA 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO)‐terminated poly(ethylene glycol) (PEG) or ‐poly(ε‐caprolactone) (PCL) (PEG11‐TEMPO or PCL23‐TEMPO) is grafted as a side chain onto a ROMP‐generated polyoxanorbornene (PONB) main backbone with bromide pendant groups (PONB20‐Br) using the NRC click reaction to yield related the brush copolymers, PONB20‐g‐PEG11 or PONB20‐g‐PCL23 catalyzed by Cu(I), Cu(0), and N,N,N′,N″,N″‐pentamethyldiethylenetriamine in N,N‐dimethylformamide at room temperature. Additionally, a ROMP‐generated brush copolymer PONB9‐g‐poly(methyl methacrylate)24 (PMMA)24‐Cl was reacted with a PEG11‐TEMPO or a PCL23‐TEMPO precursor via the NRC click reaction to yield a corresponding brush terpolymer, PONB9‐g‐(PMMA24‐b‐PEG11) or PONB9‐g‐(PMMA24‐b‐PCL23) under a similar reaction condition described above. © 2011 Wiley Periodicals, Inc.
