Abstract: An analysis of fractions extracted from polydimethylsilanes, as well as distillates obtained during the synthesis of poly(oligo)carbosilanes was carried out. By the methods of gel permeation chromatography and chromatography-mass spectrometry, the range of molecular weights in extracts and distillates, the composition and structure of compounds, as well as the sequence of their retention times on the chromatographic column were determined. It was established that the compounds extracted from polydimethylsilanes are low molecular weight cycles containing methylsilane and/or methylsiloxane units. In distillates, compared with extracts, the number of low molecular weight compounds containing individual or mixed methylsilane, carbosilane and siloxane units increases.
