|Characterization of PtBA-b-PEO-b-PtBA and PAA-b-PEO-b-PAA copolymers|
a BA, E, and AA represented the PtBA, PEO, and PAA blocks, the subscripts were the degree of polymerization of the PtBA, PEO, and PAA blocks, respectively
b BA31E227BA31 was determined by GPC in THF at 1.0 mL/min using PS as the standard; AA31E227AA31 was determined by GPC in aqueous solution of 0.1 M Na2SO4 at 0.6 mL/min using PEO standards
c Determined from 1H NMR spectra
