FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of copolymerising olefins, according to which a) a first starting olefin material is prepared, mainly consisting of Cn-olefins, and a second starting olefin material, mainly consisting of Cm-olefins, where n and m independently denote different integers from 2 to 12, and where the second starting olefin material is characterised by degree of branching of olefins defined in form of an ISO index ranging from 0 to 18, and is obtained via dimerisation of raffinate II, mainly consisting of isomeric n-butenes and n-butane, in the presence of a nickel-containing oligomerisation catalyst, and b) the first and second starting olefin materials react on a heterogeneous olefin oligomerisation catalyst based on sheet and/or framework silicates. The invention also relates to codimers obtained using said method, a method of producing alcohols according to which said olefin codimers undergo hydroformylation followed by hydrogenation of mixtures of alcohols obtained using said method. ^ EFFECT: high efficiency of the method. ^ 18 cl, 2 tbl, 1 ex |
