High viscosity sulfonic-acid-groups containing condensation products based on amino-s-triazines |
| abstract |
The invention relates to highly viscous, sulfonic acid-containing condensation products based on amino-s-triazines with at least 2 amino groups and formaldehyde, which, as a solids content of 20% by weight, have aqueous solutions having a viscosity of 500 to 100,000 cP at 20 ° C. and one pH of 8.0 to 13.0 and by a) condensation of amino-s-triazine, formaldehyde and sulfite in a molar ratio of 1: 1.9 to 2.9: 0.7 to 1.3 in aqueous solution a pH of 9.0 to 12.0 and a temperature of 50 to 90 ° C until the sulfite is no longer detectable and b) subsequent further condensation at a pH of 2.0 to 5.0 and a temperature from 50 to 100 ° C until the viscosity has the desired value. |
