FORFARANDE FOR FRAMSTELLNING AV ETT REDISPERGERBART VINYLACETAT/ETENPOLYMERDISPERSIONSPULVER

摘要

Vinyl acetate/ethylene copolymer powders are obtained by spray-drying of the corresponding aqueous polymer dispersions while simultaneously adding finely divided inorganic materials as anti-caking agents. The polymer powders thus obtained have an excellent storage stability, are easily dispersible in water and yield plastics mortars of high water resistance and plasterings made therefrom which are free from cracks.
