WebPolyglycols (Aliphatic Polyethers) Properties. Polyglycols, also called polyether glycols or polyols, are chemical compounds with the general formula HO[-(CH 2) m O-] n-(CH 2) m-OH. They are viscose liquids or waxy solids depending on molecular weight and hydroxyl content due to the weak intermolecular attractive forces (low polarity).
In organic chemistry, a polyol is an organic compound containing multiple hydroxyl groups (−OH). The term "polyol" can have slightly different meanings depending on whether it is used in food science or polymer chemistry. Polyols containing two, three and four hydroxyl groups are diols, triols, and tetrols, respectively. See more Polyols may be classified according to their chemistry. Some of these chemistries are polyether, polyester, polycarbonate and also acrylic polyols. Polyether polyols may be further subdivided and classified as See more Polyether polyols have numerous uses. As an example, polyurethane foam is a big user of polyether polyols.
