US Patent 7034089 Epoxy-functional hybrid copolymers

Versatile synthetic methodology has been established for the production of a variety of siloxane and silane-containing radial epoxy resins and intermediates. This chemical approach has been exploited to obtain a variety of hybrid organic/inorganic materials that can be described as epoxysiloxane or epoxysilane radial copolymers. The methodology can be used to access reactive, hydrophobic Si-containing resins with good organic compatibility that are structurally distinct from epoxy-functional siloxanes/silanes known in the prior art.
