FIELD: chemistry.SUBSTANCE: invention relates to a method of producing poly[(R)carbines] (R = H, alkyl, aryl), which comprises reacting a trihalide-methyl group-containing organic compound CX3R (X = Cl, Br; R = H, alkyl, aryl) with magnesium, in an ether-type organic solvent, in a mechanical activator; excess magnesium is decomposed by ammonium salts, and the obtained poly[(R)carbine] (R = H, alkyl, aryl) is separated from the solution by replacing the solvent, followed by precipitation from the solution using a hydrocarbon of general formula CnH2n+2, where n?6. The method is characterised by that, in order to eliminate the dependence of the output of the reaction product on the material and purity of the surface of components of the mechanical activator in contact with the reaction mixture, the reaction of the compound CX3R with magnesium is carried out in the presence of a catalyst, which includes at least one transition metal compound of the composition MXn (M=Fe, Co, Ni, Cu; X = Cl, Br, CN, CNS oxygen-free ligands; n=1, 2 or 3). The invention also relates to a catalyst.EFFECT: use of the present method increases output of poly[(R)carbines] (R = H, alkyl, aryl) and improves reproducibility of reactions of producing poly[(R)carbines] (R = H, alkyl, aryl) in mechanical activators of different types, by eliminating the dependence of results of such reactions on the material and state of surfaces of the mechanical activator in contact with the reaction mixture, and the catalyst increases the rate of producing poly[(R)carbines] (R = H, alkyl, aryl).6 cl, 14 ex, 1 tbl |
