TOLUENE DIISOCYANATE RESIDUE-BASED COMPOSITIONS AS FILLERS FOR POLYISOCYANATES

TOLUENE DIISOCYANATE RESIDUE-BASED COMPOSITIONS AS FILLERS FOR POLYISOCYANATES

TDI residue-based urethane-filled isocyanate compositions are produced by reacting a TDI residue satisfying specified criteria with a monofunctional alcohol in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 0.9:1 to about 1:0.9. This reaction product is...

Zusammenfassung:TDI residue-based urethane-filled isocyanate compositions are produced by reacting a TDI residue satisfying specified criteria with a monofunctional alcohol in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 0.9:1 to about 1:0.9. This reaction product is then dissolved in a diisocyanate or polyisocyanate. These TDI residue-based urethane-filled isocyanate compositions are particularly useful in the production of polyurethanes.
