How is Poly(Propylene Glycol) (CAS: 25791-96-2) typically synthesized?

Answer

Poly(Propylene Glycol)
Poly(Propylene Glycol) (PPG) is synthesized by the polymerization of propylene glycol. This process involves the repeated addition of propylene oxide to propylene glycol in the presence of a catalyst, such as a strong acid or a metal alkoxide. The reaction is typically carried out under anhydrous conditions to ensure high molecular weight and high selectivity, leading to a high yield of PPG.
