Abstract

Abstract Translated from German Pulverförmige Emulsionspolymerisate auf Basis von Acryl-monomeren mit einer Glastemperatur nicht unter 45°C lassen sich mit erhöhtem Schüttgewicht und vermindertem Feinstaubgehalt bei vermindertem Energiebedarf durch Sprühtrocknung einer vorzugsweise mehr als 50 Gew. -%igen, insbesondere mindestens 58 %igen bimodalen wäßrigen Dispersion des Emulsionspolymerisats herstellen. Powdery emulsion polymers based on acrylic monomers with a glass transition temperature not below 45 ° C can be sprayed with preferably more than 50% by weight, in particular at least 58%, aqueous bimodal aqueous dispersion of the emulsion polymer with an increased bulk density and reduced fine dust content with reduced energy requirements produce.
