Process for modifying functionality of organofunctional substrate surfaces
First Claim
1. A process for modifying the surface of an organofunctional substrate comprising reacting an organofunctional group of a silicon compound A with the surface of an organofunctional substrate to form a polar treated surface, wherein the silicon compound A comprises at least one organofunctional group and at least one chloro, alkoxy, carboxy or hydroxyl group, and further wherein said silicon compound A may react to form a polymer bearing silyl groups, then applying to the polar treated surface an organofunctional silicon compound B, wherein the silicon compounds A and B may be identical or different, the silicon compound B bears at least one chloro, alkoxy, carboxy or hydroxyl group, and the silicon compound B reacts with the polar treated surface.

Abstract
A process for modifying the functionality of organofunctional substrate surfaces by first reacting the organofunctional group of a silicon compound A with the surface of a substrate, where the silicon compound A bears at least one organofunctional group and, as other groups, bears at least one chloro, alkoxy, carboxy or hydroxyl group, then applying to the pretreated substrate an organofunctional silicon compound B, where the silicon compounds A and B are identical or different and the silicon compound B bears at least one chloro, alkoxy, carboxy or hydroxyl group. The process produces surface-modified substrates for other applications.
