POLYOL USED IN POLYURETHANES

In polymer chemistry, polyols are compounds with multiple hydroxyl functional groups available for organic reactions. A molecule with two hydroxyl groups is a diol, one with three is a triol, one with four is a tetrol and so on.

Monomeric polyols such as glycerin, pentaerythritol, ethylene glycol and sucrose often serve as the starting point for polymeric polyols. These materials are often referred to as the “initiators” and reacted with propylene oxide or ethylene oxide to produce polymeric polyols. However, they should not be confused with free radical “initiators” used to promote other polymerization reactions. The functional group used as the starting point for a polymeric polyol need not be a hydroxyl group; there are a number of important polyols which are built up from amines. A primary amino group (-NH2) often functions as the starting point for two polymeric chains, especially in the case of polyether polyols.
