Abstract
Disclosed are inorganic-organic copolymers and their preparation using polyvinylalcohol-silane coupling agents. The inorganic-organic copolymers can be prepared through the reaction of silane-coupling agents containing hydroxy groups and silane groups with organic metal compounds. The inorganic-organic copolymers are of high transparency as well as shows superb moisture barrier characteristics and hydrophilicity and can be applied as resins or film coatings for many fields, including anti-fogging agents, anti-foaming agents, lubricants, paints, anti-corrosive coatings, water-resistant coatings, plastic or metal-protective coatings.
