a
Determined by 1H-NMR spectrum in D2O.
b
Molecular weights were determined by GPC in DMF, polymethyl methacrylate standards. Mn and Mw represent number and weight average molecular weight, respectively.
c
Polymer solubility was measured by 25 mg mL−1 and described as (+) or insoluble (−) at room temperature.
