Usually using various mixtures of methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylphenyldichlorosilane in the presence of an organic solvent such as toluene. Hydrolysis is carried out at a lower temperature to obtain an acidic hydrolyzate. The initial product of hydrolysis is a mixture of cyclic, linear and crosslinked polymers, usually also containing a significant amount of hydroxyl groups. The hydrolyzate is washed with water to remove the acid, and the neutral condensate is thermally oxidized in the air or further polycondensed in the presence of a catalyst to finally form a highly crosslinked stereo network structure.
