FIELD: polymerization processes. SUBSTANCE: process comprises dissolving, in hydrocarbon solvent, monomers, hydrogen, and, separately, catalytic complex components; preliminarily mixing solutions of gas-liquid mixture containing monomers, solvents and hydrogen and solutions of catalytic complex components prior their passing into reactor and carrying out copolymerization of reaction mixture at elevated pressure and temperature. Above-mentioned preliminary mixing is accomplished in the first tubular attachment in limited- space reactor and in the second tubular attachment, said limited-space reactor has volume not exceeding 200 volumes of the first tubular attachment. Agitation in the second tubular attachment is accompanied by heat removal. EFFECT: enabled continuity of process and achieved homogeneity of copolymer. 1 dwg, 1 tbl, 2 ex
