  • Tertiary amine-containing polyols prepared in a Mannich condensation reaction using a mixture of alkanolamines
    Patent number: 5120815
    Abstract: An improved 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 an 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.
    Type: Grant

  • Melamine-alkanolamine condensates and polyurethanes prepared therefrom
    Patent number: 4939182
    Abstract: Condensates of certain amino-substituted s-triazines, formaldehyde and alkanolamines are disclosed. These condensates can be used, with or without alkoxylation, in forming polyurethanes having desirable burn properties.
