Abstract
A layered inorganic-organic polymer having the features of both inorganic and organic materials and a coating material produced therefrom. The former is produced, for example, by reacting an organoalkoxysilane having alkoxyl groups and organic groups with a metal salt or alkoxide in an alkaline solution. This reaction yields a layered inorganic-organic polymer composed of one or two sheets of tetrahedrons with a central atom of Si or a metal and a sheet of octahedrons with a central atom of a metal, part or all of the central atoms of the tetrahedrons being covalently bonded to organic groups. If the organic group is one which contains a functional group capable of polymerization, the resulting layered inorganic-organic polymer may be polymerized with a functional group to give a firm coating material. The functional group of the organic group may be bonded to an organic compound. The layered inorganic-organic polymer has both the features of inorganic materials such as high hardness and good heat resistance and the features of organic materials such as flexibility and sheet formability at room temperature. In addition, it has good affinity for organic solvents and organic substances.
