FIELD: chemical technology.
SUBSTANCE: invention describes a method for preparing metallopolycarbosilanes. Method involves interaction of polycarbosilanes with molecular mass above 200 Da and with the main chain consisting of links of the formula: [-(R)2Si-CH2-] wherein R means hydrogen atom (H), (C1-C4)-alkyl or phenyl groups with metalloorganic compounds of the formula MXz wherein M means transient metal of III-VIII group of Periodic system; z = 2-4; X means NR1 2 wherein R1 means (C1-C4)-alkyl group in organic solvent medium at temperatures from 20°C to 400°C under pressure from 5.05 MPa to 0.2 kPA. Method provides preparing fusible soluble polymers with homogeneous distribution of chemically bound metal atoms that elicit high capacity for fiber- and film-formation from solutions or melts that are hardened in thermochemical treatment and provides high yield of ceramic residue in pyrolysis (up to 85 wt.-%).
EFFECT: improved preparing method.
