Abstract: Oxyalkylated, carboxyl-containing polymers are prepared by reacting (A) a polymer which contains one or more monoethylenically unsaturated C3-C6-carboxylic acids as copolymerized units with (B) an alkylene oxide in an aqueous medium at not more than 120 DEG C. by a process in which the reaction is started at a pH of from 5.0 to 5.9 and is ended after a pH of from 5.5 to 8.5 has been reached. As a result of monitoring of the pH, the selectivity of the addition reaction of alkylene oxides with the polymers (A) is substantially improved compared with known processes.

Abstract: Preparation of mixture of alkoxylated alcohols and use thereof as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes. Preparation of a mixture of alkoxylated alcohols I R-O-(C2H4O)x-(C3H6O)y-H (I) where x is an average degree of ethoxylation of from 1 to 12 and y is an average degree of propoxylation of from 1 to 15, comprises mixing at least two mixtures of alcohols of the general formula R-O-H where one alcohol mixture carries straightchain or branched C8-C18-alkyl groups as the radical R and one other alcohol mixture carries straight-chain or branched C10-C20-alkyl groups as the radical R, subject to the proviso that the two radicals R differ by at least 0.5 in the average number of carbon atoms, and the two alcohol mixtures are present in a weight ratio of from 10:90 to 90:10, with one another and reacting this mixture first with the corresponding amount of ethylene oxide and then with the corresponding amount of propylene oxide. This mixture is useful as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes.
