Molar ratio Mannich polyols

A Mannich polyol is well characterised by the molar ratio between reactants ... 

Thus, one of the most popular Mannich polyols is based on the following molar ratios... 

The viscosity of the final Mannich polyol depends on the functionalities of the resulting Mannich bases (lower functionalities lead to lower viscosities) and on the molar ratio between the reacted PO/mol of the Mannich base. Figure 15.2 shows the variation of the Mannich polyol viscosities as a function of the molar ratio of the PO/Mannich base (Mannich base from 1 mol of nonyl-phenol, 2 mols of formaldehyde and 2 mols of diethanolamine). One observes that after the addition of one PO mol/mol of Mannich base a maximum of viscosity is obtained and by the addition of 2-5 mols of PO the viscosity decreases continuously.
