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: Acyloxybenzenesulfonic acids and their alkali metal and alkaline earth metal salts are prepared by sulfonation of phenol in the presence of a small amount of a complexing agent for the sulfonating agent SO3 or chlorosulfonic acid, followed by esterification and, if required, neutralization to give the alkali metal or alkaline earth metal salt.

Abstract: Textile goods containing synthetic fibers are washed and after-treated by a process wherein, as an antiredeposition agent, a copolymer is employed which contains, as copolymerized monomers, (a) from 50 to 90% by weight of one or more vinyl esters of C1-C4 aliphatic carboxylic acids, (b) from 5 to 35% by weight of one or more N-vinyllactams, (c) from 1 to 20% by weight of one or more monomers containing basic groups, or of salts or quaternization products of these monomers, and (d) from 0 to 20% by weight of one or more further monomers which are copolymerizable with monomers (a), (b) and (c) and are free from carboxyl and basic groups, the percentages in each case being based on the sum of the monomers, with the proviso that the percentages sum to 100.

Abstract: Alkali metal and alkaline earth metal salts of acyloxybenzenesulfonic acids of the formula I where R is a saturated or unsaturated alkyl radical of 1 to 17 carbon atoms or is phenyl which is unsubstituted or monosubstituted or disubstituted by alkyl of 1 to 3 carbon atoms, halogen, methoxy or nitro, are prepared by neutralization, by a method in which a liquid acyloxybenzenesulfonic acid of the formula I and an aqueous solution of an alkali metal or alkaline earth metal hydroxide, carbonate or bicarbonate are combined in water, at from 0 DEG to 60 DEG C. and while mixing thoroughly, so that the pH is kept at from 2.5 to 7.0, and, if desired, the resulting salt is isolated from the aqueous solution in a conventional manner.
