FIELD: chemistry of polymers. SUBSTANCE: carbosilane compounds with unsaturated groups selected from carbosilane dendrimer or superbranched carbosilane are first made to react with methyl bidecyl silane at molar ratio of unsaturated groups of carbosilane to methyl bidecyl silane from 2 to 1.1 in the presence of platinum catalyst at 20-80 C, and the resulting methyl bidecyl silyl derivative is methylated with alkyl lithium in organic solvent at 20-80 C. EFFECT: use of polylithium derivatives of carbosilane compounds as anionic polymerization initiators having good solubility and stability in organic solvents. 7 cl, 10 ex
