Description générale

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.
