Abstract
Process for the preparation of new polyglycol ether derivatives, characterized in that chains of polyglycol ether are introduced, preferably with the help of ethylene oxide, into compounds derived from nitrogen-containing bases, of formula ** (See formula) ** where m means a small whole number, and a whole number that is at most 2, in whose compounds are linked with nitrogen atoms to at least one hydrogen atom and at least two aliphatic or cycloaliphatic radicals, which together contain at least 20 carbon atoms and, precisely, at least one hydrocarbon radical, and at most one acyl radical derived from a fatty acid or cycloaliphatic acid, in which compounds, in addition, all the carbon atoms bonded with an oxygen atom are linked only each with a single oxygen atom, and, eventually, transforming the products thus obtained into salts.
