Popis:	Cyclolinear permethylpolycarbosilanes were synthesized for the first time by the reaction of 1,3- and 1,4-dihydrodecamethylcyclohexasilanes H2Si6Me10 with α,ω-diallylpermethyloligo-silanes All(SiMe2)nAll (n = 1–6) in the presence of Karstedt’s catalyst. The molecular weight characteristics, thermal and thermooxidative stability, and the spectral properties of the synthesized polymers were studied. The dependence of the yield and the molecular weight of the synthesized polymers on the number of the SiMe2 units in the linear oligosilane fragment of the main chain was established.
