Abstract

The invention concerns a dispersion powder composition which is redispersible in water and is made from water-insoluble organic polymers, the composition being characterized in that it contains 0.1 to 30% by wt., relative to the weight of the organic polymers, of one or more silicon compounds which are dispersible in water and which have a boiling point at normal pressure of 160 degrees C., selected from the group comprising the silanes, polysilanes, oligosiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes and polysilylenedisiloxanes. The invention also concerns methods for manufacturing such compounds and their use.
