The molecular weights of the copolymers had been calculated from the 1H NMR knowledge by comparing the peak intensities of the methylene protons of PEG with the methylene protons of PCL
An amphiphilic block copolymer composed of a PCL block as the hydrophobic aspect and a PEG block as the hydrophilic element was synthesized through ring-opening polymerization utilizing hydroxylterminated PEG as…
