Application
聚(丙二醇)可用：
- 增塑剂，因为它不结晶，具有较低的玻璃化转变温度，并具有生物相容性。例如，它可以用于聚乳酸的塑化。
- 制备从盐单胞菌细胞中回收 Ectoine 的水双相体系。
- 研究超分子聚合物（PPG）向常规聚合物（PPO）的虚拟转变。

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
