一般描述
聚丙二醇(PPG)是一种聚醚。由环氧丙烯通过开环聚合而成。聚丙二醇毒性较低，可用作皮革涂饰材料的分散剂，也用作表面活性剂、湿润剂，用于药物制剂。
应用
聚丙二醇的用途如下：
- 作为软钢在酸性溶液中的缓蚀剂。
- 作为起始材料，通过前端聚合(frontal polymerization)合成环氧树脂/聚氨酯杂化网络。

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.

The designed DNA sequences can make DNA-b-PPO undergo in situ transition between diblock and triblock upon pH changes, consequently, induce a morphology-shifting from spherical micelles to nanofibers. This process is reversible and the assembled structures have been characterized by CD

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
