Special Issue Information

Dear Colleagues,

The industrial development of polyolefin and synthetic rubber is an important symbol for the process of high polymer industry. The catalyst is the core technology for the synthesis of polyolefin and synthetic rubber as their product compositions and structures depend on the characteristics of the used catalyst, and this makes the irreplaceable position of catalysts in the development of polymer materials. At present, the main challenge for polyolefin and synthetic rubber is to develop novel catalysts with high activity and high selectivity. Through the innovation of catalyst structure, the selection of functional monomer and new polymerization technology, the microstructure of polyolefin and synthetic rubber can be accurately regulated, so as to obtain polyolefin and synthetic rubber products with different properties and application fields. It is important that the microstructure of polyolefin and synthetic rubber can be accurately regulated through the innovation of catalyst structure, the selection of functional monomer and new polymerization technologies, so as to obtain polyolefin and synthetic rubber products with different performances for many applications.

This special issue will focus on the latest progress and advances in the field of catalysts for polyolefin and synthetic rubber. We are looking forward to accepting articles about novel catalysts for polyolefin and synthetic rubber, including but not limited to manuscripts on polymerization process technology, reaction mechanisms, and molecular kinetics, which will greatly promote the industrial progress of polyolefin and synthetic rubber generation.

I greatly believe that we will be able to receive many submissions and contribute our best for obtaining a good special issue in Catalysts.

Hydrogenated carboxyl nitrile rubber (HXNBR) is endowed with superior mechanical performance and heat–oxygen aging resistance via emulsion hydrogenation of its precursor, i.e., carboxyl nitrile rubber (XNBR). Herein, a ruthenium-based catalyst was prepared to achieve the direct catalytic hydrogenation of XNBR latex. The effects of a series of hydrogenation conditions, such as catalyst dosage, solid content and reaction temperature, as well as the hydrogen pressure, on the hydrogenation reaction were investigated in detail. We found that the hydrogenation rate fell upon increasing the solid content of the XNBR latex, with an XNBR conversion rate of 95.01 mol% in 7 h with 11.25 wt% solid content. As the reaction temperature was increased, the hydrogenation rate first increased and then decreased. The fastest reaction hydrogenation rate was reached at 140 °C, with an XNBR conversion of 95.10 mol% in 5 h. The hydrogenation rate was positively related with the hydrogen pressure employed in the reactor. In view of the safety and cost, a pressure rate of 1300 psi was considered optimal. Similarly, the hydrogenation rate can also be enhanced by adding more catalyst. When 0.05 wt% catalyst was added, the fastest hydrogenation rate was achieved. In summary, the following optimum hydrogenation conditions were determined by using a synthesized ruthenium-based catalyst: 11.25 wt% solid content of XNBR latex, 140 °C of reaction temperature, 1300 psi of hydrogen pressure and 0.05 wt% catalyst. The vulcanization, mechanical performance, aging resistance and oil resistance of the produced HXNBR under the above reaction conditions were systematically investigated. Full article
