|polyglycol/carbowax;[高分子]聚乙二醇;聚氧乙烯
polyethylene glycol(聚乙二醇,缩写为PEG)是一种由乙二醇重复单元通过醚键连接形成的水溶性高分子化合物。以下是其详细解释:
化学结构与性质
聚乙二醇的分子式为$text{HO(CH}_2text{CH}_2text{O)}_ntext{H}$,根据聚合度(n)不同,分子量可从几百到数万不等。例如,PEG 400的分子量约为400。它易溶于水和有机溶剂,具有润滑性、吸湿性和生物相容性。
应用领域
衍生物与变体
聚乙二醇可通过化学修饰形成多种衍生物,例如聚乙二醇十一烷二羧酸酯(polyethylene glycol undecandicarboxylate)、聚间苯二酚二缩羟乙酸乙二醇酯(polyethylene glycol resorcinol diglycidyl ether)等,用于特定领域的功能材料开发。
如需更全面的信息(如不同分子量PEG的详细用途),可参考相关化学数据库或行业标准文件。
Polyethylene glycol(聚乙二醇) is a synthetic, water-soluble polymer made by the polymerization of ethylene oxide. It has a wide range of applications in industries such as pharmaceuticals, cosmetics, and food.
Polyethylene glycol is a compound used in a variety of products, including laxatives, skin creams, and toothpaste. It is also used in the production of some pharmaceuticals, such as tablets and capsules, as a solubilizer and lubricant. Polyethylene glycol is commonly abbreviated as PEG.
