Polyethylene glycols - polymer of ethylene glycol
The product is used to manufacture plasticizers, in chemical, textile, rubber, metal-working industries.
Polyethylene glycols is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. The structure of polyethylene glycols is commonly expressed as H−(O−CH2−CH2)n−OH.
