Stable compositions of water-soluble amino-and alkenyl-functional organosiloxanes, process for their preparation and their use

摘要

The present invention relates to a stable composition of water-soluble organosiloxanes obtained by reacting;a) a water-soluble amino-functional alkoxysilane with at least one water-insoluble alkenyl-functional alkoxysilane;b) by adding water to form a mixture, and;c) removing the alcohol formed during step b) from the mixture,;where the amino-functional alkoxysilane and the water are used in the reaction at least in amounts such that substantially all of the alkoxy groups of the water-insoluble silane can react and such that when a resulting composition is diluted with water, essentially no alcohol is liberated by hydrolysis, and the composition, during an/or after the reaction, has a pH of from 2 to 6, the pH being preferably adjusted by adding an organic or inorganic, optionally aqueous, acid. In addition, the present invention discloses a process for the preparation of such a composition and also its use.
