摘要：
Polyorganosilanes are prepared through contact reaction of an organodihalosilane with alkali metal fine particles dispersed in an organic solvent. the reaction solution is adjusted to an acidity of pH 3 to 7 before or after the step of deactivating the excess alkali metal in the reaction solution. The alkali metal halide is removed from the reaction solution by dissolving it in water. Formation of insoluble components is minimized.
