Protocol
Preparation Method of Polyethylene Glycol
Polyethylene glycol is produced by the stepwise addition of ethylene oxide and water or ethylene glycol. When preparing polyethylene glycol with a larger molecular weight, polyethylene glycol with a lower molecular weight is often used as the initiator. The polymerization reaction can be carried out in gas phase or liquid phase polymerization.
