Abstract

Abstract Translated from German Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung von Kondensationsprodukten aus A) 1 Mol eines hochveretherten Hexamethylolmelamins mit B) 3 bis 6 Mol eines Thiols der allgemeinen Formel worin R 1 einen perfluorierten Alkylrest mit 4 bis 14 C-Atomen und X den Ethylen- oder Isopropylenrest bedeuten, wobei die Komponenten A) und B) unter Temperatursteigerung auf mindestens 145°C während mindestens40 Minuten miteinander umgesetzt werden. The present invention describes a method for producing condensation products from A) 1 mole of a highly etherified hexamethylolmelamine B) 3 to 6 mol of a thiol of the general formula in which R 1 is a perfluorinated alkyl radical having 4 to 14 carbon atoms and X is the ethylene or isopropylene radical, components A) and B) being reacted with one another with an increase in temperature to at least 145 ° C. for at least 40 minutes. Die Kondensationsprodukte sind in Form von wäßrigen Dispersionen zum Öl- und Wasserabweisendmachen von Fasermaterial geeignet. The condensation products are suitable in the form of aqueous dispersions for rendering fiber material oil and water repellent.
