Claim:
1. A composition comprising a chlorinated polysilane having at least one direct Si—Si bond, whose substituents consist of chlorine and hydrogen or consist of chlorine and in whose composition the atomic ratio of substituent:silicon is at least 1:1, wherein the polysilane consists of rings and chains with a proportion of branching sites which, based on the total composition, is >1 mass %, the polysilane has a RAMAN molecular vibration spectrum of I 100 /I 132 <I, where I 100 denotes the Raman intensity at 100 cm −1 and I 132 denotes the Raman intensity at 132 cm −1 , and the 29 Si NMR spectra of the composition has its significant product signals in the chemical shift range from +23 ppm to −13 ppm, from −18 ppm to −33 ppm and from −73 ppm to −93 ppm, and wherein the polysilane is a complex substance mixture having an average molar mass of 300-900 g/mol, and wherein the average chain length of the composition corresponds to n=3-9.
