Volume – 5 ml total; reaction solvent – DMF; T = 90 °C; M1 – BA, M2 – MPDL; L – Me6TREN; [I] = [EBiB] = 5 mM; RI – radical initiator: V40 (Tt1/2=10h = 88 °C); entries 1–2: [M1] = 1 M, [M2] = 0.5 M; entry 5: [M1] = 0.3 M, [M2] = 0.3 M; RO – % of MPDL monomer in ring-opened form to ring-closed form; fMPDL – fraction of MPDL incorporated into the polyether backbone, final M̄n was measured by DMF GPC with MALLS detector.
