Abstract: PRODUCTION OF ORGANICALLY MODIFIED FINELY DIVIDED ALKALINE EARTH METAL AND EARTH METAL SILICATES AND SILICAS BY WET PRECIPITION OF SUCH SILICATES AND SILICAS FROM ALKALI METAL SILICATE SOLUTIONS WITH AQUEOUS SOLUTIONS OF ALKALINE EARTH METAL OR EARTH METAL SALTS OR ACIDS, PREFERABLY AT TEMPARATURES BETWEEN ABOUT 10 AND 90* C. IN THE PRESENCE OF WATER SOLUBLE REACTIVE POLYMERIC MATERIALS, FOR INSTANCE, POLYMERS CONTAINING THE REACTIVE AMINO, HYDROXYL, CARBOXYL, AMIDE OR KETO GROUPS. THE THUS OBTAINED MODIFIED SILICATES AND SILICAS CAN BE FURTHER MODIFIED BY EFFECTING REACTIONS WITH THE REACTIVE GROUPS OF THE BOUND POLYMERS IN THE SILICATES AND SILICAS.
