The orthogonality of RAFT and ROMP chemistries are exploited for a highly efficient “grafting through” strategy to afford cylindrical molecular brushes. The ROMP of α‐norbornenyl‐functionalized poly( t ‐butyl acrylate) macroRAFT chain transfer agents, catalyzed by a modified 2nd generation Grubbs' catalyst, achieved completion in minutes under air. Following hydrolysis, functionalizable water‐soluble poly(acrylic acid) molecular brushes were afforded.
