Abstract
Solid alkali metal salts of organosilanols and/or their hydrolysis/condensation products are prepared by hydrolysis of organosilanes in water and in the presence of a basic alkali metal salt. The products contain predominately methyl and ethyl organic groups, and Cor higher hydrocarbon groups as well. The solid salts effectively hydrophobe building materials, while being easily mixed with water.
