“…In study [6], a mixture of thermoplastic elastomer and petroleum polymer resins (up to 8 %) is used for the modification of asphalt. With an increase in the concentration of PPR obtained on the basis of С 9 fraction, the softening temperature of the formulation increases, however, permeability and ductility are significantly reduced.…”

“…Petroleum polymer resins (PPRs) are used as cheap synthetic substitutes for products of natural origin (vegetable oils, colophony, albumin), phenol-formaldehyde and indene-coumarone resins, in paint-and-varnish anti-corrosion [1][2][3] and asphalt bitumen formulations [4][5][6]. A factor limiting the wider use of such hydrocarbon resins is a high color index (up to 100 mg I 2 /100 ml on an iodometric scale).…”

This paper investigates the production of hydrocarbon resins by emulsion oligomerization of the С9 fraction hydrocarbons in liquid by-products of oil refining. Such oligomers have a wide range of applications as film-forming agents in paints and anti-color coatings. Emulsion oligomerization was carried out using emulsifiers of the first and second kind. The study was performed at different values of the reaction temperature of the reaction duration, the intensity of agitation; concentrations of the emulsifier; С9:water fraction ratio. The resulting products were estimated according to the following indicators: the yield, unsaturation degree, softening temperature, mean molecular weight, color. Statistical analysis was carried out, the correlation of parameters of emulsion oligomerization and the yield and characteristics of oligomers was established. Given that, it would be possible to establish the optimal conditions for emulsion oligomerization and predict the properties of the products obtained. Specifically, it was established that the yield of hydrocarbon resins does not correlate with the reaction temperature (0.15 and 0.30) and the concentration of emulsifiers (0.08 and 0.03). It was proven that in the intervals studied the variable yield of oligomers depends on the duration of the reaction (correlation 0.88 and 0.81). In the case of oligomerization in the reverse emulsion, a significant correlation with the yield is also demonstrated by agitation intensity (0.51) and a С9:water fraction ratio (0.51). That has made it possible to derive an equation of the yield multiple linear regression dependent on the most significant process parameters. The high values of the yield and bromine number correlation (0.94 and 0.93) give grounds to argue about the progress of oligomerization reaction. The relationship among the characteristics of oligomers has been confirmed. This indicates the possibility of directed adjustment of certain characteristics of hydrocarbon resins.

This paper investigates the production of hydrocarbon resins by oligomerization in solution and suspension of the C9 fraction of by-products from oil refining. The disadvantage of existing technologies for oligomers by free radical oligomerization is the use of high reaction temperatures. The application of N-replaced amino peroxides as low-temperature initiators and a suspension oligomerization technology can reduce the temperature and duration of the reaction. The correlation between oligomerization parameters and yield and characteristics of oligomers has been established. Owing to this, it will be possible to set optimal conditions and predict the properties of the resulting products. The high values of the yield and bromine number correlation in oligomerization in solution (–0.98 and –0.95) and suspension (–0.83 and –0.80) indicate the course of the oligomerization reaction. The main factor influencing oligomerization in solution is the reaction temperature (correlation 0.80). The softening temperature of oligomers is in the range of 349‒353 K and does not depend on the oligomerization conditions in the solution (correlation indicator 0.18). Suspension oligomerization in the studied intervals does not depend on temperature (correlation −0.08) and initiator concentration (correlation 0.40). It is proved that in the studied intervals of variables, the yield of oligomers depends on the duration of the reaction (correlation 0.88). The color indicator of suspension oligomerization products at the studied intervals varies slightly and is 20–30 mg I2/100 ml. The established optimal conditions make it possible to effectively use oil refining by-products by synthesizing light oligomers. Under the established optimal conditions, the product yield is 22.7 % with oligomerization in solution and 19.4 % with suspension oligomerization.

“…This is because the oligomeric resin has a higher glass transition temperature (T g ) than the rubber matrix [ 16 , 17 , 18 ]. Moreover, due to its low molecular weight [ 19 , 20 , 21 ] and low softening point [ 22 , 23 ], the oligomeric resin can improve the processability of composites at a certain processing temperature higher than their softening point. However, F-SSBR was developed in recent years and there is little research on oligomeric resin being used in F-SSBR.…”

Polymerized, functionalized solution styrene–butadiene rubber (F-SSBR) is a new type of polymerized styrene–butadiene rubber solution containing specific terminal groups, which can be used in treads for high performances. However, the wet skid resistance related to safety, the rolling resistance to energy consumption, and the wear resistance to service life are often contradictory and form the performance “magic triangle”. In this work, oligomeric resins, including Coumarone resin, C9 resin, C5/C9 resin and a styrene-α-methyl styrene copolymer (SSC), were used as tire functional additives and selected to replace treated distillate aromatic extract (TDAE) to improve the performances of silica-filled F-SSBR composites. The C9 resin, C5/C9 resin and SSC could enhance the modulus at 300% and tensile strength of the F-SSBR composite. The four resins could improve the wet skid resistance and wear resistance of the composites. However, Coumarone resin caused poor silica dispersion in the F-SSBR matrix and eventually, the lower modulus, higher loss factor at 60 °C and the higher heat buildup in the composite were comparative to the composite with TDAE. Furthermore, the synergistic effect of the C5/C9 resin and SSC was found to improve the mechanical performance of the composites and it resulted in higher tensile strength and modulus, and a lower heat buildup, compared to the case when only TDAE was used. It is noted that the properties “magic triangle” was broken by the C5/C9 resin and SSC, and the C5/C910T15 increased the wet skid resistance by 21.7%, fuel-saving rate by 2.3%, and wear resistance by 8.3%, while S20T5 increased the wet skid resistance by 30.4%, fuel-saving rate by 7%, and wear resistance by 25% compared with CG.
