Fig. 1 — Switch catalysis using TCA1/PO. a Switch catalysis reaction scheme. Conditions: [SalcyCrCl]/[PPNCl]/[CHD]/TCA1/PO = 1:0.5:10:200:400, Tol-d₈ (5 M), 60 °C; b normalised polymerization conversion vs. time plots for the reaction of TCA1/PO (Supplementary Figs. 1 and 2, Supplementary Table 1. The maximum conversion was limited to 65% due to monomer loss at a high number of aliquots) and c evolution of M_n and Ð (relative to PS standards; Supplementary Figs. 6 and 7, Supplementary Table 2)
