ABSTRACT A process for preparing Mannich polyols is disclosed. The process involves capping a Mannich condensate of a phenolic compound or an amino- substituted s-triazine with a small quantity of ah alkylene oxide in the absence of an alkylene oxide polymerization catalyst, prior to heating the condensate to elevated temperatures at which polycondensates are formed. The capped Mannich condensate is then alkoxylated to form the desired polyol.
