Method for making polyethylene glycol carbonates |
| abstract |
A method for making an alkyl polyethylene glycol carbonate by the step of reacting mono-alkyl polyethylene glycol (mPEG) such as mPEG having an average molecular weight of 20,000 grams. Per mole and a polydispersity of less than 1.1, a chloro formate such as p-nitrophenyl chloroformate, an aromatic solvent such as toluene and an amine such as tripentylamine. And, a method for making a multi-armed polyethylene glycol carbonate by the step of reacting a multi-armed polyethylene glycol having at least one hydroxyl group, a chloroformate, an aromatic solvent and an amine. |
