PROCESS FOR PRODUCING POWDERS

摘要

Disclosed is a process for producing a metal oxide-based polycondensation powder which comprises cohydrolyzing (a) a silane compound having one or more alkoxyl groups and containing a polymerizable unsaturated bond and (b) a metal alkoxide, in a flowing aqueous medium. Moreover, if this process is carried out in a flowing aqueous medium having an inorganic powder dispersed therein, there is obtained a composite powder having polymerizable unsaturated groups and containing the inorganic powder.
