Polyalkylene glycols (PAGs) are a versatile class of synthetic polymers widely utilized in numerous industrial applications due to their unique properties. These polymers are synthesized through the polymerization of alkylene oxide monomers, including ethylene oxide, propylene oxide, and butylene oxide.

Petroleum-based mineral oils are essential in various applications, particularly in mechanical systems, where they serve as lubricants. One important aspect of these oils is their performance at low temperatures, which can be enhanced by adding pour point depressants.
