FIELD: chemistry of polymers. SUBSTANCE: claimed invention describes preparation of methyl chlorosilanes for synthesis of polymeric organosilicon materials. The claimed invention makes it possible to increase yield of trimethylchlorosilane by using, as catalyst of disproportionation of direct synthesis products, methylchlorosilanes aluminium gammma-oxide, copper, zinc, antimony, lead chloride and silicon, the ratio of components being or follows (wt%): 20-40 aluminium gamma oxide; 3-6 copper; 0.3-0.6 zinc; 0.03-0.06 antimony; 0.8- 1.5 lead chloride; and silicon balance. EFFECT: increased yield of trimethylchlorosilane. |
