摘要
A catalyst for sol-gel methods using metal alkoxide comprises a mineral acid or its anhydride and an organic base, said organic base being a tertiary amine that is substantially insoluble in water and soluble in organic solvents. A sol-gel method using the above-mentioned catalyst comprises a step of hydrolyzing a metal alkoxide with a subsequent polycondensation of hydrolyzate thereof using the catalyst, resulting in a polymer containing gel.
