|polyglycol/carbowax;[高分子]聚乙二醇;聚氧乙烯
polyethylene glycol(聚乙二醇,縮寫為PEG)是一種由乙二醇重複單元通過醚鍵連接形成的水溶性高分子化合物。以下是其詳細解釋:
化學結構與性質
聚乙二醇的分子式為$text{HO(CH}_2text{CH}_2text{O)}_ntext{H}$,根據聚合度(n)不同,分子量可從幾百到數萬不等。例如,PEG 400的分子量約為400。它易溶于水和有機溶劑,具有潤滑性、吸濕性和生物相容性。
應用領域
衍生物與變體
聚乙二醇可通過化學修飾形成多種衍生物,例如聚乙二醇十一烷二羧酸酯(polyethylene glycol undecandicarboxylate)、聚間苯二酚二縮羟乙酸乙二醇酯(polyethylene glycol resorcinol diglycidyl ether)等,用于特定領域的功能材料開發。
