| How are polyether polyols made? |
Polyether polyols are made by the reaction of epoxides with compounds having active hydrogen atom. Polyester polyols are made by the polycondensation reaction of multifunctional carboxylic acids and polyhydroxyl compounds. They can be further categorized according to their end use. |
