Patent ID: 7358316

Claim:
A process for preparing an organic silicate polymer comprising: a) a polymerization step, in absence of homogenizing organic solvents, of mixing and reacting organic silane compounds with water in the presence of a catalyst to hydrolyze and condense the silane compounds at a temperature of 0° C. to 100° C. to obtain an organic silicate polymer having a network structure, wherein the organic silane compound is one or more selected from a group consisting of a compound represented by Chemical Formula 1, a compound represented by Chemical Formula 2, organic silane oligomers thereof, and a mixture thereof, R 1 m R 2 n SiX 4-m-n Chemical Formula 1 where each of R 1 and R 2 which may be the same or different is hydrogen, alkyl group, fluorine-containing alkyl group, alkenyl, or aryl, X is a hydrolysable group, halogen, alkoxy, or acyloxy, and m and n are integers of from 0 to 3 satisfying 0≦m+n≦3, and R 3 p Y 3-p Si-M-SiR 4 q Z 3-q Chemical Formula 2 where each of R 3 and R 4 which may be the same or different is hydrogen, alkyl group, fluorine-containing alkyl group, alkenyl, or aryl, Y and Z, which may be the same or different, is a hydrolysable group, halogen, alkoxy, or acyloxy, M is an organic bridged unit including methylene, ethylene, propylene, or phenylene, and p and q are integers of from 0 to 2; b) an aging step of adding organic solvents to the polymerization product obtained in the step a) and heating the product at a temperature of 15° C. to 100° C., and c) a drying step of removing the organic solvents and the water from the aged polymerization product to obtain a solid phase organic silicate polymer.
