a

Specified by supplier.

b

Determined by MALDI mass spectroscopy.

c

Determined by SEC. Weight average dn/dc was used with dn/dc = 0.068 for PEO and 0.087 for PPO.

d

Determined from molar ratios by 1H NMR spectroscopy.

e

Calculated from number-average molecular weight (Mn,2) and weight fraction of PEO (wPEO,2). For triblock Pluronics, NEO represents the number of repeat units of EO in one PEO block.
