Abstract
Materials containing the reaction products of a cyclic azasilane with water and a compound or polymer containing an isocyanate or epoxy functional group and methods for their synthesis are provided. Stable mixtures containing a cyclic azasilane and a compound or polymer containing an isocyanate or epoxy functional group according to invention are stored under anhydrous conditions. The invention also provides a novel class of materials, mono and bis(cycloaza)disiloxanes comprising one or two cyclic structures bridged by an Si—O—Si bond.
