Characterization of PtBA-b-PEO-b-PtBA and PAA-b-PEO-b-PAA copolymers
Samplesa Mnb Mw/Mnb Mn,NMRc DPc
BA31E227BA31 25,700 1.06 18,250 62
AA31E227AA31 15,460 1.15 14,760 62

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
