Beschreibung

Allgemeine Beschreibung

Poly(propylene glycol) (PPG) is a hydrophobic polyether that is widely used in various biomedical areas such as preparation of biocompatible polyurethanes and lubricious coatings on absorbable sutures.

Anwendung

Poly(propylene glycol) can be used:

• As a precursor to synthesize biodegradable poly(ether-ester) networks via UV photopolymerization.
• As a stabilizing agent in the preparation of metal nanoparticles such as gold nanoparticles.
• As a starting material to prepare silane-terminatedpoly(urethane-urea)s (SPUR) polymers.
