Abstract
The invention provides a process for the manufacture of addition products from nitrogen containing compounds which contain at least one ethylenically unsaturated radical and organopolysiloxanes which contain hydrogen atoms bonded to silicon, and a process for treating fibrous materials with the resultant addition product composition. The process comprises adding to the organopolysiloxanes allylmelamines, allylguanamines, monoallyl- or diallylureas, monoallyl- or diallylthioureas or cyclic urea derivatives which contain at least one ethylenically unsaturated radical. The addition is carried out in the presence of methylolated aminoplast formers which can also be etherified with lower alcohols, or in the presence of the cited unsaturated compounds in their methylolated form. The unsaturated compounds can also be used direct in methylolated and etherified form. The resultant addition products are used in an aqueous emulsion or an organic solvent for the treatment of fibrous materials. The treated materials are provided with a good wash-resistent water repellent finish.
