1.4聚乙二醇/聚氧乙烯嵌段基于聚氧乙烯(PEO)的两亲性共聚物代表了迄今为止研究最早且研究最多的高分子表面活性剂,不同组成和不同分子量的PEO和PPO的二、三嵌段共聚物已经作为工业表面活性剂出现在市场上很长一段时间了(如BASF生产的Pluronic),过去的二十年出现了一些关于它们性质的综述~([5,6,8,9,21-23,105])。PEG/PEO聚合物主要通过2种方法合成:乙二醇(EG)的缩合或环氧乙烷开环阴离子聚合。当聚
1.4 Polyethylene glycol / polyoxyethylene block Polyethylene oxide (PEO) -based amphiphilic copolymer represents the earliest and most studied polymer surfactant to date, with different compositions and molecular weights of PEO and PPO Second, triblock copolymers have been on the market for an extended period of time as industrial surfactants (such as Pluronic® from BASF) and some reviews of their properties over the past two decades have been reported. ([5, 6, 8, 9, 21-23, 105]). PEG / PEO polymers are synthesized mainly by two methods: condensation of ethylene glycol (EG) or ring opening anionic polymerization of ethylene oxide. When poly
