Abstract
(DE)
Das neue Verfahren zur Herstellung von Polykondensat-Lösungen auf Basis von Polyamidamin/Epichlorhydrin-Harzen liefert Produkte mit sehr niedrigem Gehalt an organischen Chlorverbindungen, insbesondere einem Gehalt von 1,3-Dichlorphenol-2-propanol von < 0,1 %, bei hoher Wirksamkeit und guter Lagerstabilität.
(EN)
The invention relates to a novel method of producing polycondensate solutions based on polyamide amine/epichlorhydrine resins. According to said method, products are obtained that have a very low content in organic chlorine compounds, especially products with a 1,3-dichlorophenol-2-propanol content of < 0.1 %, which are highly effective and have a good storage stability.
(FR)
L'invention concerne un nouveau procédé permettant de préparer des solutions de polycondensat à base de résines de polyamidamine/épichlorhydrine. Ce procédé permet d'obtenir des produits à très faible teneur en composés chlorés organiques, qui ont notamment une teneur en 1,3-dichlorophénol-2-propanol de < 0,1 %, à haut degré d'efficacité et présentant une bonne stabilité au stockage.
