polyol
This term is a technical chemical designation used primarily in polymer science and industrial chemistry. It describes a specific class of alcohols characterized by the presence of several hydroxyl groups, which allows them to act as versatile building blocks for creating complex molecular networks.
In practical application, polyols are most frequently discussed in the context of polyurethane production. They are viewed as the reactive partner to isocyanates, where the number and position of the hydroxyl groups determine the final physical properties of the resulting plastic or foam, such as rigidity or elasticity.
