Patent number: 5753733Abstract: The invention concerns a dispersion powder composition which is redispersible in water and is made from water-insoluble homopolymers or copolymers of preferably ethylenically unsaturated monomers and one or more organosilicon compounds plus, optionally, other additives such as protective colloids and anti-blocking agents. The composition is obtained by: a) polymerizing one or more monomers in the presence of 0.1 to 30% by wt., relative to the total weight of the monomers, of one or more silicon compounds which are dispersible in water and which have a boiling point at normal pressure of >160.degree. C., selected from the group comprising the silanes, polysilanes, oligosiloxanes, polysiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes and polysilylenedisiloxanes and: b) spray-drying the product thus obtained, either before or after addition of the additives mentioned.Type: GrantFiled: September 18, 1996Date of Patent: May 19, 1998Assignee: Wacker-Chemie GmbHInventors: Herbert Eck, Heinrich Hopf, Klaus Adler, Franz Jodlbauer, Guenter von Au
