Determined by MALDI mass spectroscopy.

Determined from molar ratios by ¹H NMR spectroscopy.

Calculated from number-average molecular weight (M_n) and weight fraction of PEO (w_PEO). For triblock Pluronics, N_EO represents the number of repeat units of EO in one PEO block. Triblock N_PO and N_EO values differ slightly from those provided by the supplier, as reported in refs 27 and 28.
