Abstract
Abstract The cross-linked macromolecular polyethers containing ionic bonds are obtained by reacting polyhydric phenols which contain amino groups (Mannich bases) on the one hand with compounds which contain on average more than one epoxide group per molecule, and on the other hand with organic compounds which contain at least 2 halogen atoms. The reaction is on the one hand a polyaddition, and on the other a polyquaternization. The adducts manufactured in this way have a reduced tendency to take on a static charge and can be used with advantage in the textile and paper sectors.
