Polypropylene glycol - Wikipedia

Polypropylene glycol is produced by ring-opening polymerization of propylene oxide.The initiator is an alcohol and the catalyst a base, usually potassium hydroxide.When the initiator is ethylene glycol or water the polymer is linear. With a multifunctional initiator like glycerine, pentaerythritol or sorbitol the polymer branches out.
