Kinetically stable halogenated polysilanes include mixture of compounds having respectively at least four silicon atoms bound together, the substituents thereof comprising chlorine, and chlorine and hydrogen, and in the composition thereof, the atomic ratio of substituent to silicon is at least 1:1, wherein a) the kinetically stable halogenated polysilanes have a kinetically high stability in relation to oxidative splitting by chlorine, and the degree of conversion at temperatures of 120° C. within 10 hours with an excess of chlorine gas at 1013 hPa does not exceed 30 mol %, and b) the kinetically stable halogenated polysilanes have a percentage of branching points in the polysilane molecules of more than 8 mol %.
Kinetically stable halogenated polysilanes comprising a mixture of compounds having more than three silicon atoms in the backbone with in each case at least four interconnected Si atoms whose substituents comprise chlorine or chlorine and hydrogen and in whose composition an atomic ratio of substituent to silicon is at least 1:1, where
