ABSTRACT:
The invention includes a sulfolane functional silane comprising a sulfolane ring, an alkoxy group, a hydrocarbon backbone, and a silyl moiety. An oxygen atom of the alkoxy group is bound to the sulfolane ring, and the hydrocarbon backbone has one to fifty carbon atoms and is bound by its first terminal carbon atom to a carbon of the alkoxy group and by its second terminal carbon atom to the silicone atom of the silyl moiety. The silyl moiety comprises at least one hydrolyzable group and/or a non-hydrolyzable group that is a substituted or unsubstituted siloxane group. A method to stabilize a silane solution is described and includes adding the sulfolane functional silane of the invention to a solution containing silane hydrosylates.
