^a Number-average molecular weight of polymer determined by ¹H NMR spectroscopic analysis. ^b Polydispersity index of polymer determined by GPC analysis in THF. ^c Number-average degree of polymerization of PBA block determined by ¹H NMR spectroscopy. ^d Volume fraction of the PBA block estimated from the values of ${\overline{M}}_{\mathrm{n},\mathrm{NMR}}$ and mass density ρ_m. ^e Number-average degree of polymerization of the PEO block determined by ¹H NMR spectroscopy. ^f Volume fraction of the PEO block estimated from the values of ${\overline{M}}_{\mathrm{n},\mathrm{NMR}}$ and mass density ρ_m. The ρ_m value was 1.08 g/cm³ for linear PBA homopolymer and 1.12 g/cm³ for linear PEO homopolymer [31].
