General description
聚乙二醇（PEG）是亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合很容易地合成，得到一系列分子量和各种端基。当交联成网时，PEG可具有很高的含水量，形成“水凝胶”。可以通过电离辐射使PEG交联或通过PEG大分子单体与反应性链端共价交联来引发水凝胶形成。PEG是适合生物学应用的材料，因为它不会引发免疫反应。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
Application
PEG被用于修饰治疗性蛋白和肽，以增加溶解度、降低毒性。
光聚合的PEG水凝胶在制备生物活性和免疫隔离的屏障用于细胞包封方面具有新兴应用。
