It was advised to use aliphatic, cycloaliphatic, aromatic petroleum resins and their derivatives obtained by oxidation of resins with a mixture of hydrogen peroxide and acetic acid as bitumen polymer-modifiers. Petroleum resins were obtained by ionic polymerization of unsaturated compounds of liquid pyrolysis products under the influence of titanium tetrachloride-diethylaluminium chloride catalyst. It was established that the maximum values of adhesion of modified bitumen coatings to metal substrates, corresponding to the minimum values of the wetting angle of the metal surface coated with solutions of bitumen compositions with different content of the polymer modifier were achieved using oxidized resins. All modified bitumen coatings have low water absorptivity and high acid resistance, alkali resistance and salt resistance, which allow using them as protective coatings

The paper presents the results of studies of the flow properties of viscous compositions consisting of polyvinyl alcohol, polymeric oil resin, and water. After a freeze-thaw cycle three-component cryogels are formed from them. Mechanical, thermal, physical, and chemical properties of the resulted elastic samples are studied. The prospects of using hydrophobic cryogels filled with polymeric oil resin as a binder component for road pavement construction are presented

The paper presents the results of an investigation of cryogels filled with an oil-polymer resin. The rheological properties of three-component emulsion, as well as the elastic and thermophysical properties of filled cryogels are studied. A comparative analysis of the physico-chemical properties of cryogels depending on the nature of filler is carried out.

Possibilities of synthesis and properties of the products of the ozonated petroleum resins modification by ethanolamines was considered. It is founded that ethanolamines interact both with decomposition products of the ozonized groups obtained from ozonated resins, and directly with the ozonized groups themselves. The obtained modified petroleum resins can be used as adhesive and film-forming components in paint materials.

The possibility of using epoxidized petroleum resins for modification of bitumen was shown. The dependence of the properties of coatings based on polymeric-bitumen compositions of the number of modifiers, hardening agent and the curing temperature was investigated. The optimum process parameters for polymeric-bitumen compositions were identified. The resistance of the coatings to different environments was investigated.

The purpose of this study is to investigate the dicyclopentadiene fraction of liquid pyrolysis product oligomerization with the use of the modified catalytic system based on titanium alkoxides. The choice of reaction catalyst is specified by searching the ways of obtaining petroleum resins with the improved performance characteristics and the possibility of low-temperature polymerization. The use of monosubstituted titanium chloride as a catalyst allows obtaining light resins, films on the base of which are smooth, glossy and have good technical characteristics: adhesion 1 point, resilience 10cm.

Processes for producing lower olefins are critically examined. It is noted that pyrolysis of various types of hydrocarbon is still the main process of obtaining ethylene and propylene, and is accompanied by the formation of considerable amounts of by-products, such as liquid pyrolysis products. We present an analysis of domestic and foreign scientific, technical, and patent information pertaining to the rational use of petrochemical production by-products, aimed at obtaining hydrocarbon (petroleum) resins. We consider the raw materials involved in obtaining the resins, and generalize data on existing methods of obtaining resins using thermal, initiated, and ion (catalyst) polymerization.

This work demonstrates the possibility of obtaining modified aliphatic resin (PRC5) by means of petroleum resin oxidation by peracetic acid. We have experimentally determined oxidation conditions that lead to producing resin with maximum epoxy and acid numbers. Ratio of «oxidative system: PRC5» is 0.5:1, process duration is 2 hours. The modified resin structure is determined by IR and NMR spectroscopy.

Formation of active site is the main process in all initialization reactions (including metalorganic Lewis acid action). The process of interaction of vinyl monomers with metalorganic Lewis acid (MLA) consists of several equilibrium stages [1], such as formation of active charged particles and their counter ions and subsequent addition of the charged pair to the monomer. The initial equilibrium is usually slow process while the further attack of the monomer (initialization) is very fast and is comparable with the rate of the reaction of chain growth. Moreover, presence of the cationogenic contaminations in the reaction mixture causes a lot of confusion to chemistry of cationic processes. Now we can consider more or less confidently only two possible ways of initialization of polymerization of vinyl monomers by MLA: direct initialization and co-initialization [2-5].

The possibility of obtaining modified petroleum resin, whose structure is determined by means of 1H-NMR spectroscopy and GLC, by copolymerization of various fractions of liquid products of pyrolysis and butyl methacrylate under the influence of cationic catalysts is shown. The yield of modified resins decreases in the following pattern: C 9 > DF > CF. The number of aromatic units reduces as their unsaturation increases in the same pattern. The modified petroleum resins can be used as a film-forming materials in the paint-and-lacquer materials.

The in situ oxidation of the petroleum resin under soft condition was investigated. The oxidation was carried out by using hydrogen peroxide and acetic acid as the oxidants, and sulphuric acid as a catalyst for in situ formation of the peracetic acid. The infrared spectroscopy analysis shows the changes in the molecular structure: the amount of the epoxy, hydroxyl and carbonyl groups increases and the number of unsaturated bonds decreases. The new method for the determination of the reaction rate constant was presented. For the determination of the reaction rate constants the relative intensity of absorption band in the area of epoxy and carboxyl groups vibration was used. Obtained data are in a very good correlation with the reaction rate constants obtained with the epoxy and acid number valuation. That allows to conclude the validity of using presented algorithm. Kinetic calculation indicates the occurrence of the oxidation reaction by the first order. According to average reaction rate constant the process has a high selectivity for epoxy groups.

This work represents the results of obtaining modified petroleum resin based on dicyclopentadiene fraction. The modification is carried out by means of resin oxidation by the Prilezhaev's method. The possibility of epoxidation of dicyclopentadiene double bonds during the process in the residual hydrocarbons is experimentally established. Dependences of acid, bromine and epoxy numbers on oxidation process duration at various «oxidative system: resin PRDF» component ratio is found. The modified resin structure is determined by IR and NMR spectroscopy.
