CA 2182202

Dispersion powder composition which is redispersible in water and is based on water-insoluble homo- or copolymers of preferably ethylenically unsaturated monomers and one or more organosilicon compounds and, if appropriate, further additives, such as protective colloids and antiblocking agents, obtainable by a) polymerization of one or more monomers in the presence of 0.1 to 30% by weight, based on the total weight of the monomers, of one or more organosilicon compounds which are diapersible in water and have a boiling point under normal pressure of > 160°C, from the group consisting of silanes, polysilanes, oligosiloxanes, polysiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes and polysilylenedisiloxanes and b) spray drying of the emulsion thus obtained, if appropriate before or after addition of the additives mentioned.

L'invention concerne une composition pulvérulente en dispersion, pouvant être redispersée dans l'eau, à base d'homopolymères et de copolymères insolubles dans l'eau de monomères de préférence éthyléniquement insaturés et à base d'un ou plusieurs composés d'organosilicium ainsi que, le cas échéant, d'autres additifs tels que les colloïdes protecteurs et les agents antibloquants, ladite composition pouvant être obtenue par: a) polymérisation d'un ou de plusieurs monomères en présence de 0,1 à 30 % en poids, rapporté au poids total des monomères, d'un ou plusieurs composés d'organosilicium pouvant être dispersés dans l'eau, présentant un point d'ébullition supérieur à 160 DEG C sous pression normale, provenant du groupe des silanes, polysilanes, oligosiloxanes, polysiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes, disiloxanes de polysilylène, et b) par séchage par pulvérisation du produit ainsi obtenu, le cas échéant avant ou après incorporation des additifs mentionnés.
