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。

This study examines the in vitro characteristics of a crosslinking polymer system for cerebral aneurysm embolization. The polymeric material is composed of poly(propylene glycol)diacrylate (PPODA) and pentaerythritol tetrakis(3-mercaptopropionate) (QT), formulated with the liquid contrast agents Conray™ or Omnipaque™ 300.

We show here that complementary interactions can suppress mesoscopic order and thus lead to a counterintuitive change in material properties. We present results for telechelic supramolecular polymers based on poly(propylene oxide) (PPO), thymine (Thy), and diaminotriazine (DAT). The self-complementary systems
