The process of modifying road bitumen obtained from the residues of Ukrainian oils processing with rubber crumb has been studied. The dependence of the softening temperature, ductility, penetration, and elasticity of the three-component bituminous composition “bitumen : linseed oil : rubber crumb” on its formulation has been examined. Based on the mentioned composition a new type of cold-applied bitumen roofing has been developed. A process flow diagram for the production of modified bitumen and special-purpose bituminous composition has been developed.

The suspension oligomerization of the unsaturated hydrocarbons of the C9 fraction of liquid by-products of diesel fuel pyrolysis initiated by N-(tert-Butylperoxymethyl)-4- chloroaniline was investigated. The influence of reaction conditions (reaction temperature and time, mixing intensity, dispersed phase content, initiator concentration) on the yield and physico-chemical characteristics of hydrocarbon resins was determined. The optimal reaction conditions were selected. The temperature dependence of the relative and dynamic viscosity of the obtained hydrocarbon resin solutions was determined.

We investigated the production of petroleum resins by suspension oligomerization of С9 hydrocarbon fraction initiated by aliphatic aminoperoxides. The reaction mixture consisted of a dispersion medium (water), a dispersed phase (C9 fraction), an initiator, which is soluble in the dispersed phase, and a suspension stabilizer. In the range of variables studied, reaction temperature (313–353 K) and initiator concentration (0.032–0.096 mol/l) do not have a significant effect on the oligomers yield. The process conditions most influencing the course of suspension oligomerization of the С9 fraction are as follows: stirring intensity (Re=2290–13450) with the correlation index of 0.88, reaction time (30–240 min) with the correlation index of 0.87 and the ratio of dispersed phase to dispersed medium (1:1–1:4) with the correlation index of –0.91. The correlation between the yield and bromine number (correlation index of –0.82) confirmed the passage of oligomerization reaction via the unsaturated bonds of the monomer. The hydrocarbon resins obtained by low-temperature suspension oligomerization were mainly cooligomers of styrene and its derivatives. As a result of suspension oligomerization at low temperatures, products were obtained which were characterized by a light color (color index of 10–20 mg I2/100 ml), a molecular weight of 505–530 and a softening point of 347–354 K.
