Popis:	Controlled synthesis of high molecular weight cyclolinear polycarbosiloxanes (PCCS) is considered, using the following reactions sequence: (1) anionic polymerization of vinyldimethylphenylsilane, (2) replacement of the Ph group in polyvinyldimethylphenylsilane (M n=83.900,M w/M n=1.48) by a Cl group to prepare polyvinyldimethylchlorosilane (PVMCS), and (3) hydrolytic intramolecular condensation of PVMCS. The formation of carbochain polymer with predominantly six-membered carbosiloxane rings is demonstrated (M n=81.400,M w/M n=1.54).
