ABSTRACT:
A process for producing porous glass, which comprises preparing a reaction solution containing a metal alkoxide or its oligomer and an organic polymer, hydrolyzing and polymerizing the metal alkoxide or its oligomer in the solution to obtain a gel, and calcining the gel to obtain porous glass, wherein the organic polymer has compatibility with the solution of the metal alkoxide or its oligomer, undergoes phase separation during the hydrolysis-polymerization step and is substantially free from formation of precipitates.
