Process for the preparation of activated polyethylene glycols |
| abstract |
A process for preparing activated polyethylene glycols is disclosed. In some embodiments, the process includes reacting a molten polyethylene glycol with an activator. In other embodiments, the process includes reacting a polyethylene glycol with an activator in the absence of a solvent. The process may be carried out in an inert gas atmosphere, at a temperature at least 10° C. above the melting point of polyethylene glycol, and/or with the activator provided in molar excess of the polyethylene glycol. The invention further provides activated polyethylene glycols produced by this process and their use in a variety of pharmaceutical, medical, cosmetic and chemical applications. |
