Polyethylene glycol testing method

WebBased on three protons in methoxy polyethylene glycol, the molecular weight of PEG-PCL was 7.7 kD (2,000 + 100/2 × 114 = 7,700). 1 H-NMR of PEG-PCL-COCHCH 2 is shown in Figure 1C. Peak shifts were according to PEG-PCL . The peaks at 5.5–6.5 ppm (−OCO−CHCH 2, 3.59H) were attributed to three protons in the acryloyl-substituted group.
