Multi-block polymer syntheses by switch catalysis. a Synthesis of pentadeca(15) block polymer; b GPC traces showing evolution of molar mass values with block sequence and c Plot showing block number against mass, Mn, and dispersity value, Ð (GPC). Reaction conditions: [SalcyCrCl]/[PPNCl]/[CHD]/TCA1/PO = 1:0.5:15:200:400, Tol-d8 (5 M), 60 °C, 3–5 days. For each subsequent monomer addition, 200 equiv. of TCA1 and 400 equiv. of PO were added
