In the case of a mixture of two oligo-polyols with different functionalities (fj and f2), the equivalent functionality, fe, of the oligo-polyol mixture is calculated using the general formula ... 

Because the functionality of an oligo-polyol for elastic polyurethane is 2-3 hydroxyl groups/mol, the general formula shown in Figure 4.1 becomes the formula shown in Figure 4.2. 

Polyalkylene oxide polyether polyols are the most important group of polyols for PU, representing around 80% of the total oligo-polyols production. The general formula of a polyalkylene oxide poly ether polyol is presented in Figure 4.3.
