“…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.

“…Currently, pyrolysis C 9 is mainly used for the production of the nine-carbon aromatic hydrocarbon resin. The potential of olefin-rich liquid pyrolysis gasoline and the corresponding C 9 and C 5 fractions as feed stocks for HR manufacturing through catalytic polymerization has been explored by various researchers in the literature. − However, the reported methods have limitations including the low yield, being limited to the laboratory scale, and the limitations in scaling-up, which make them industrially unrealistic. Furthermore, the economics and risks of industrial-scale HR manufacturing are not clear.…”

Conversion of olefin-rich side streams of petroleum distillate cracking operations, pyrolysis gasoline (pygas), to hydrocarbon resins (HRs) represents a promising technology to upgrade the pygas byproduct and facilitate pygas valorization. Several methods have been reported for the synthesis of C 9 HRs on a laboratory scale, but none has been implemented on a commercial scale. Owing to the lack of information on C 9 -HR production know-how, the current publicly available technical and financial performance analyses regarding industrial-scale C 9 HR manufacturing are insufficient to justify its feasibility. Herein, the large-scale synthesis of C 9 HR from the steam-cracked petroleum-derived C 9 fraction by two proposed catalytic polymerization processes has been developed. Two C 9 -HR manufacturing processes are divided into two processing areas, which include synthesis and purification/product recovery sections. The P-HO process is based on the catalytic co-oligomerization of the C 9 fraction as the feed, which ends after the alkali decomposition of the catalyst followed by product recovery by vacuum distillation. The P-HE process uses the same reactor, which ends after catalyst filtration followed by product recovery using vacuum distillation. The laboratory-scale experiments were performed to collect inputs for process simulation. A set of targeted experiments including the increase of the scale from the laboratory (V L = 0.0005 m 3 ) to pilot plant (V P = 0.1 m 3 ) were performed and the impact of scaling up the processes from the lab and bench to the pilot scale at equal process conditions was investigated. The differences in the HR production rate between the two scale types for the P-HO scenario are slightly greater than for the P-HE scenario. On the basis of data derived from the experimental work, a model of a large-scale installation for the production of C 9 HR with the production rate of 160 metric ton (MT)/year was developed using the Aspen Hyprotech System (HYSYS) v8.8 simulation program. The obtained data from the relevant literature and vendor were used for process equipment design and pricing. Economic feasibility showed that the P-HO scenario has more efficiency and less risk-taking than the P-HE scheme (because of valuable net present value (NPV) $10 977 billion, larger internal rate of return (IRR) 44.01% at $1900/T HR selling price, and less fluctuation against sensitivity analysis parameters).

Carbon 9 (C9) resin is a major by-product of the petrochemical industry and is rich in unsaturated hydrocarbons. By copolymerization with maleic anhydride (MAH), the product MAH-C9 was used as a carbon foaming agent. Combining MAH-C9 with ammonium polyphosphate (APP), which served as an acid and a gas source, an intumescent flame-retardant system was introduced into thermoplastic polyurethane (TPU). Flammability evaluation indicated that 4.5 wt% APP and 0.5 wt% MAH-C9 helped TPU achieve the maximal limiting oxygen index value of 25.9%, passing UL-94 V-0 rating. Total smoke release was decreased from 1,884.4 m 2 /m 2 for neat TPU to 833.0 m 2 /m 2 and char formation was promoted. The mechanical loss brought by 5 wt% APP was a little recovered by 4.5 wt% APP/0.5 wt% MAH
