Claims
- 1. A treated fluoroaluminosilicate glass comprising an acid-reactive arganofluoroaluminosilicate particulate glass having an ion-containing, siloxy-containing coating, made by the process comprising the steps of
- a) mixing finely-divided fluoroaluminosilicate glass with a non-neutral aqueous silanol solution, and
- b) drying the glass.
- 2. The glass of claim 1, wherein the silanol is ionic and at least 0.1 percent hydrolyzed.
- 3. The glass of claim 1, wherein the silanol is nonionic and at least 0.1 percent hydrolyzed.
- 4. The glass of claim 1, wherein the solution is acidic and the silanol is ethylenically unsaturated.
- 5. The glass of claim 1, wherein the solution is basic and the silanol is ethylenically unsaturated.
- 6. The glass of claim 1, wherein the solution is acidic and the acid is borne on the silanol.
- 7. The glass of claim 1, wherein the solution is acidic and the acid is borne on the silane from which the silanol is formed.
- 8. The glass of claim 1, wherein the solution is basic and the base is borne on the silanol.
- 9. The glass of claim 1, wherein the solution is basic and the base is borne on the silane from which the silanol is formed.
- 10. The glass of claim 1, wherein the silanol has one or more pendant carboxylic acid groups.
- 11. The glass of claim 1, wherein the solution is acidic and the acid is present as a separate component of the solution.
- 12. The glass of claim 1, wherein the solution is basic and the base is present as a separate component of the solution.
- 13. A glass according to claim 1, wherein the silanol has the formula R.sub.n Si(OH).sub.4-n wherein R is a non-hydrolyzable polymerizable organic group and n is one to three.
- 14. A glass according to claim 1, wherein the silanol is ethylenically-unsaturated and carboxylate ion-containing.
- 15. A glass according to claim 1, wherein the silanol has the formula CONHR.sup.5 OOCR.sup.4 CH.sub.2, wherein R.sup.4 is H or CH.sub.3 and R.sup.5 is a divalent alkylene linking group.
- 16. A glass according to claim 1, further comprising a coating of an additional organic compound.
- 17. A glass according to claim 16, wherein the additional organic compound comprises a functional group selected from the group consisting of acrylates and methacrylates.
- 18. A glass according to claim 16, wherein the additional organic compound has a weight average molecular weight per double bond of between 100 and 5000.
- 19. A glass according to claim 16, wherein the additional organic compound comprises polyethyleneglycol dimethacrylate.
