Preparation of glass-like materials from aqueous silica systems by polymerization and contemporaneous dehydration

Claim 1

THE METHOD OF PREPARING A SPINNING AND COATING SYRUP COMPOSITION OF HIGH MOLECULAR WEIGHT GLASS-LIKE MATERIALS WHICH INCLUDES THE STEPS OF: PREPARING AN AQUEOUS SYSTEM SATURATED WITH COLLOIDAL SILICA, ALL OF THE SILICA BEING PRESENT IN PARTICLES OF LESS THAN ONE MICRON IN SIZE, ADDING LESS THEN 2% OF A STABILIZING AGENT COMPRISING AN AQUEOUS DISPERSION OF ABOUT 1.3% OF A SOLID REACTION PRODUCT PREPARED BY TAKING ABOUT 36 PARTS BY WEIGHT OF ETHYL METHACRYLATEE, ABOUT 0.36 PART VINYL ACETATE, ABOUT 0.4 PART AMMONIUM PERSULFATE AND ABOUT 1.2 PARTS SODIUM SUCCINATE, REACTING THE MIXTURE IN AN AQUEOUS MEDIUM AT ABOUT 52-55*C. TO FORM A LATEX AND THEN REACTING THE LATTER WITH ABOUT 70 PARTS OF AQUEOUS 35% ACETIC ACID SOLUTION SO THAT IT IS COPOLYMERIZED UNTIL THE MIXTURE CONTAINS APPROXIMATELY 30% BY WEIGHT OF SOLID REACTION PRODUCTS; ABOUT 0.65% POLYDIMETHYSILOXANE FLUID HAVING A VISCOSITY OF 1000 CENTISTOKES AT 25*C., ABOUT 0.072% METHYL SILICONATE, MATERIAL COMPRISING A METHYL SILICONATE SELECTED FROM THE GROUP OF SODIUM AND POTASSIUM METHYL SILICONATE, ABOUT 1.5% AMMONIUM ACETATE, AND ABOUT 92.25% OF A THREE PERCENT AQUEOUS AMMONIUM HYDROXIDE SOLUTION, ADDING AN AQUEOUS SLURRY CONTAINING DISPERSED PARTICLES OF GLASS-FORMING OXIDES HAVING MAXIMUM DIMENSIONS WITHIN THE RANGE FROM ABOUT 4 TO 120 MICRONS AND HAVING AN AFFINITY FOR ABSORPTION ON COLLOIDAL SILICA PARTICLES; ADJUSTING THE ACIDITY OF THE AQUEOUS SYSTEM TO A PH VALUE GREATER THAN 7, WHEREBY THE OXIDE JUST STARTS TO FLOCCULATE IN THE FORM OF THE HYDROXIDE.
