Beschreibung
Zusammenfassung:	The present invention pertains to a water-redispersible polymer powder composition based on at least one synthetic polymer and at least one natural latex. Preferably, the polymer powder contains up to about 90 wt.% of at least one water- insoluble, synthetic polymer, up to about 90 wt.% of least one natural latex, about 0 to 50 wt.% of at least one protective colloid, about 2 to 50 wt.% of at least one filler and/or anti-caking agent, as well as optionally further additives. In addition, the invention pertains to a process for the preparation of the polymer powder composition, the use thereof as an additive in building material compositions, as well as building material compositions containing the polymer powder composition. Cette invention concerne une composition en poudre de polymère redispersible dans l'eau à base d'au moins un polymère synthétique et d'au moins un latex naturel. De préférence, la poudre de polymère renferme jusqu'à environ 90 % en poids d'au moins un polymère synthétique insoluble dans l'eau, jusqu'à environ 90 % en poids d'au moins un latex naturel, environ 0 à 50 % en poids d'au moins un colloïde protecteur, environ 2 à 50 % en poids d'au moins une charge et/ou un antiagglomérant, et d'autres additifs éventuels. L'invention concerne par ailleurs un procédé de préparation de la composition en poudre de polymère, son utilisation comme additif dans des compositions pour matériaux de construction, et des compositions pour matériaux de construction contenant la composition en poudre de polymère.
