A method for preparing olegourethanacrylates having the general formula +TR where is a radical of a telogen; X is H, CH3 or a halide; R is a radical of glycol, bis-phenol, amino alcohol; R' is a radical of polyamine; R'' is a radical of polyol; R'' is R' if the telogen contains group; R''' is R'' if telogen contains - N(Y)H group; n is the number characterizing the degree of polycondensation of the oligourethanacrylate equal to zero, unity, or a whole number greater than unity, consisting in carrying out a reaction of a non-equlibrium polycondensation of chloroformiates of polyols with polyamines and telogens, which are chloroformiates of monoesters of alkyleneglycols and acids of the acrylic series, chloroformiates of monoesters of bis-phenols and acids of the acrylic series, monoaminoalkyl esters of acids of the acrylic series, N-substituted monoaminoalkyl esters of acids of acrylic series, in the medium of organic solvents or in a system of an water-organic solvent, in the presence of acceptors of hydrogen chloride which is liberated in the reaction.
