WebPoly (ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. 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.
