Abstract

A process of: providing a polyfunctional compound selected from polyisocyanate, polyacrylate, and polyepoxy; and reacting the polyfunctional compound with a hydroxyl- or amine-terminated silyl-containing compound. The polyfunctional compound and the silyl-containing compound are at least difunctional. A thermoset made by this process.
