a
Solvent: THF/DMSO = 3/2, Temperature: 60°C.
b
Mn denotes number average molecular weight.
c
Determined from the 1H NMR results.
d
Mw denotes weight average molecular weight. dDetermined from the following equation: Mn(calcd) = Mw(EO)[EO]0/[CADEG]0 + Mw(CADEG) = 44.05 [EO]0/[CADEG]0 + 238.28.
e
Determined from the SEC results.
