AQUEOUS SOLUTION ADHESIVES OF ORGANOSILICON COPOLYMERS

摘要

This invention is concerned with organosilicon copolymers having a recurrent unit of the general formula wherein R" represents a group selected among the groups -OH, -¢O!-¢NH!+ and -¢O!- ¢Me!+, Me being an alkali metal or an alkaline earth metal, and more than 50 % of the units are substituted by units, RV being a hydrogen atom or a hydrocarbon residue containing 1 to 20 carbon atoms. These copolymers can be added to silanes of the general formula (Y-Rp)a X4-a-b to form aqueous solutions of silicon compounds having improved properties for use as coatings on metal, inorganic-oxidic materials or plastics or as adhesion promoters between polymers and inorganic-oxidic materials.
