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.
Claims22
A condensate which is the reaction product of reactants consisting essentially of an amino-substituted s-triazine, about 0.9 to about 3.5 moles of formaldehyde per mole of amino-substituted s-triazine and about 0.75 to about 1.5 moles of at least one alkanolamine per mole of formaldehyde.
A hydroxyl-terminated compound containing a plurality of terminal hydroxylalkyl groups or terminal hydroxyl-terminated poly(oxyalkylene) groups attached to the residue, after removal of at least two hydroxyl hydrogen atoms, of a condensate which is the reaction product of reactants consisting essentially of an amino-substituted s-triazine, formaldehyde and at least one alkanolamine.
A polyether polyol initiated by a condensate which is the reaction product of reactants consisting essentially of an amino-substituted s-triazine, formaldehyde and an alkanolamine.
The polyisocyanate-based polymer of claim wherein said reaction mixture further comprises a blowing agent.
The polyisocyanate-based polymer of claim wherein said reaction mixture further comprises an additional polyol.
The polyisocyanate-based polymer of claim wherein said polyisocyanate comprises a polymethylenepolyphenylenepolyisocyanate.
The polyisocyanate-based polymer of claim which is a rigid polyurethane foam.
The polyisocyanate-based polymer of claim wherein said reaction mixture further comprises a blowing agent.
The polyisocyanate-based polymer of claim wherein said reaction mixture further comprises an additional polyol.
The polyisocyanate-based polymer of claim wherein said polyisocyanate comprises a polymethylenepolyphenylenepolyisocyanate.
