A polyol is an alcohol containing multiple hydroxyl groups. In two technological disciplines the term polyol has a special meaning: food science and polymer chemistry.n 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.
A polyether polyol is the polymeric reaction product of an organic oxide and an initiator compound containing two or more active hydrogen atoms.ther commonly used initiators for the manufacture of flexible foam polyols are listed below. 2.17 Blends of these initiator compounds are also used. 2.18-2.19. In actual practice, two side reactions preclude the production of a pure polyol from any chosen initiator compound.
