 The results of an experimental study of the oligomerization process of a mixture of unsaturated hydrocarbons of fractions C5 and C9, initiated by organic peroxide compounds, are presented. These fractions are formed as non-target products during the pyrolysis of straight-run gasoline in the production of ethene. The influence of the main technological parameters - reaction temperature and duration, type and concentration of the initiator, as well as the mass ratio of hydrocarbons [C5 fraction] : [C9 fraction] - on the yield and properties of the obtained resin was analyzed. As a result of the study, the optimal conditions for the process were determined: temperature 448 K, duration 6 h, di-tert-butyl peroxide concentration 0.05 mol/dm³. Under these parameters, a resin with a 33% yield based on raw materials is obtained, the characteristics of which meet the requirements of the paint and varnish industry for petroleum polymer resin.
