一般說明
聚丙二醇是丙二醇和水的加成聚合物。它由化学式HO(C3H6O)nC3H6OH进行表示，其中n代表氧丙烯基团的平均数。聚丙二醇可溶于水和某些有机溶剂中（例如脂族酮和醇），不溶于醚和大多数脂族烃。
應用
聚丙二醇（PPG）被广泛用作消泡剂。例如，它可以用来控制苏云金芽孢杆菌基生物农药生产（从污水污泥中分离）中的泡沫。
它可以用于制备聚氨酯（PU）弹性体。例如，它可以用于合成具有良好吸声性能的 PU 弹性体。
PPG-2000 可作为柔性链段用于制备PU 基自修复聚合物网络。这些网络在软电子领域得到了应用。

特點和優勢
- 长而灵活的烷基促进链的迁移，这有利于快速自愈。
- 存在于聚合物两侧的甲基改善了水中的乳化性。

The controlled atom transfer radical polymerization of an ionic liquid, 1-(11-acryloylundecyl)-3-methyl imidazolium bromide (ILBr), from both ends of a telechelic poly(propylene oxide) (PPO) macroinitiator, end-functionalized with bromoisobutyryloyl is reported. The resulting highly water-soluble triblock, poly(ILBr-b-PO-b-ILBr) is multistimuli responsive. This new
