PROCESS FOR THE PREPARATION OF ACTIVATED POLYETHYLENE GLYCOLS |
摘要 |
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 Degree Celcius 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.
