Preparation of crosslinked or branched organopolysilane (containing at least one silicon unit) comprises reacting a silane compound with an elementary metal (alkali or alkaline earth metal) and treating the reaction mixture, after terminating the reaction, with a mineral (poly silicic acid, silicates or alumosilicate) at at least 50[deg]C for at least 30 seconds. Preparation of crosslinked or branched organopolysilane (containing at least one silicon unit of formula (RSi?=), (=Si=), (R 2Si=) and optionally (R 3Si-)) comprises reacting silane compound of formula (RSiX 3), (SiX 4), (R 2SiX 2) and optionally (R 3SiX) with an elementary metal (alkali or alkaline earth metal) and treating the reaction mixture, after terminating the reaction, with a mineral (poly silicic acid, silicates or alumosilicate) at at least 50[deg]C for at least 30 seconds. R : H or 1-18C hydrocarbon residue; and X : F, Cl or Br. |
