General description

Poly(propylene glycol) (PPG) is a polyether. It is prepared by ring-opening polymerization of propylene oxide. PPG is less toxic and used as a dispersant in leather finishing, as a surfactant, wetting agent, and in drug formulations.

Application

Poly(propylene glycol) can be used as a:
  • Corrosion inhibitor for mild steel in acid solution.
  • Starting material to synthesize epoxy resin/polyurethane hybrid networks via frontal polymerization.
It can also be used to prepare poly(PEG/PPG/PTMC urethane) thermogels for sustained release of doxorubicin.

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
