Abstract:
1. A method of making a weak acid-neutralized solid or a weak acid-neutralized aqueous solution thereof of an amino-alkoxy-modified silsesquioxane (amino AMS), an amino/mercaptan co-AMS, amino/blocked mercaptan co-AMS or mixtures thereof, and having the formula wherein w, x, y and z represent mole fractions, z does not equal zero, at least one of w, x or y must also be present, and w+x+y+z=1.00; wherein at least one of R the method comprising the steps of: (a) combining as a reaction mixture: b) allowing the reaction mixture to react for about 0.5 hours to about 200 hours to form an amino alkoxysilane-modified silsesquioxane; and (c) recovering the amino alkoxysilane-modified silsesquioxane from the reaction mixture; (d) optionally adding a weak acid having a pK
