Abstract
A targeted molecular weight of an organopolysiloxane is obtained in a two stage hydrolysis by hydrolyzing a chlorosilane with from 0.002 to 0.6 mol of water in a first step in the presence of alcohol, in which the pressure and/or temperature are adjusted such that following further hydrolysis in a second step, the targeted molecular weight is obtained.
