The oligomerization in solution and suspension oligomerization of the fraction C9 of liquid by-products of pyrolysis of diesel fuel is initiated by 2- (third-butylperoxymethylamineo) acetate acid have been studied. The nature of the effect of oligomerization, the concentration of the initiator, the temperature and duration of the reaction to the output and the physicochemical characteristics of the obtained oligomers were clarified. The optimal technological parameters of the process of oligomerization of the fraction C9 were selected.

The paper presents the results of the study of copolymerization of 2-hydroxyethylmethacrylate (HEMA) with polyvinylpyrrolidone (PVP) under the action of two-component initiation systems of iron (II) sulfate/radical type initiator. The influence of the nature of the radical initiator (In) in the FeSO4/In system on the behavior of the polymerization of HEMA/PVP compositions, structural parameters of the polymer matrix network and properties of hydrogels based on pHEMA-gr-PVP copolymers were established.

The production of a hydrocarbon resins (co-oligomers) by low-temperature dispersion co-oligomerization of C9 fraction of diesel fuel pyrolysis liquid by-products was researched. This method allows to reduce the temperature of the process. The synthesis was carried out by emulsion and suspension co-oligomerization. The main regularities of the suspension and emulsion oligomerization of the hydrocarbon fraction C9 are established. The effect of temperature, initiator concentration and process duration on the yield, physical and chemical properties of synthesized oligomers were investigated.

The fundamental drawbacks of world industrial such us petrochemical and reprocessing are instability of the properties and inhomogeneity of product lots over the year. The principle of formulating the replacements for the stock is one of the main causes why the quantity does not meet the replacements of the standards. The tendency toward a permanent increase in cost of the feedstocks is also observed on the world market.

Two samples of brominated multi-walled carbon nanotubes [(Br)n-MWCNTs] produced by the plasma-chemical technique were involved in the liquid-phase initiated oxidation of cumene. The powerful catalytic effect of (Br)n-MWCNTs has been confirmed to recommend the substances for the use in oxidation of alkyl aromatic hydrocarbons as active additives. Obviously this phenomenon originates from the peculiarities of electronic configuration of (Br)n-MWCNTs pattern.
