POLY(PROPYLENE GLYCOL) AVERAGE MN CA. 2 000 (C005B-027860)

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.
