Polyol - Wikipedia
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, [1] triols, [2] and tetrols, [3][4] respectively.

There are different Polyols groups based on the type of monomer that makes them similar to polyester polyols, polyether polyols, aromatic or aliphatic polyols. Alternatively, polyols may be grouped based on their end use like high molecular weight polyols and lower molecular weight polyols as described below.
