Coordination cross-linking gadolinium salt/acrylonitrile-butadiene rubber composite: Its preparation, characterization, and functional properties

Abstract

A novel rubber composite of acrylonitrile‐butadiene rubber (NBR) filled with gadolinium salt (GS) particles was prepared for the first time and vulcanized via coordination reactions. The resulting materials exhibit good mechanical properties. Structural analyses indicate that the composite is a kind of elastomers based on coordination cross‐linking interactions between the nitrile groups (–CN) of NBR and gadolinium ions. The mechanical properties of vulcanized GS/NBR rubber are altered when the cross‐link density is changed in the composites. These materials show good irradiation resistance because of the introduction of GS. POLYM. COMPOS., 34:1013–1019, 2013. © 2013 Society of Plastics Engineers

Synergistic Effect of Copper Sulfate and Tetramethylthiuram Monosulfide Induced Metal‐Coordination Cross‐Linking in Nitrile–Butadiene Rubber

“…Rubbers, which possess a unique range of properties, are renowned for strategically significant materials because of their of nitrile-containing polymers was carried out in non-solution systems, in which the metal cations were incorporated by simple compounding. [12,15,[20][21][22] By incorporating metal cations (such as Cu 2+ , Zn 2+ , Co 2+ , and Ce 2+ ) into polymers (such as nitrilebutadiene rubber [NBR], XNBR, ABS/NBR, and PLA/NBR), the 3D cross-linking networks are formed where the traditional vulcanization method of sulfur curing or peroxide is replaced by the coordination cross-linking. [7,18,20,[23][24][25][26] The novel crosslinking network not only improves the mechanical properties of polymers but also endows excellent reversibility due to the coordination interaction in polymers.…”

Crosslinking behavior and enhanced mechanical properties of acrylonitrile‐butadiene rubber composites by incorporating aluminum ammonium sulfate particles

“…Wu et al expanded the coordination crosslinking rubber into nonsolution system for the first time . After that, substantial progress has been achieved toward the development of high performance and functionality of coordination crosslinking rubber . In those studies, acrylonitrile‐butadiene rubber (NBR) was usually crosslinked by the coordination bonds of CN group and a variety of transitional metal ions, such as copper ion, cobalt ion, rare earth ion, and so on.…”

[12][13][14][15] In those studies, acrylonitrile-butadiene rubber (NBR) was usually crosslinked by the coordination bonds of CN group and a variety of transitional metal ions, such as copper ion, cobalt ion, rare earth ion, and so on. Nevertheless, the utilization of main-group metal ions, such as Al 3+ , has not been explored on the crosslinking of NBR.…”
