Flammability of butadiene-acrylonitrile rubbers
Journal of Thermal Analysis and Calorimetry, 2004Abstract The paper discusses the test results of butadiene-acrylonitrile rubber, Perbunan NT 1845 and Perbunan NT 3945, flammability and properties that characterise these elastomers under fire conditions. The flammability was tested by means of oxygen index and thermovision methods.

Cure characteristics, mechanical and morphological properties of natural rubber/virgin acrylonitrile–butadiene rubber (NR/NBRv) and natural rubber/recycled acrylonitrile–butadiene rubber (NR/NBRr) blends were investigated. The properties of NR/NBRv and NR/NBRr blends were studied at five different ratios of virgin and recycled NBR content [i.e., 95/5 ...

Oxidation of Butadiene-Acrylonitrile Rubbers
Rubber Chemistry and Technology, 1962Abstract 1. The authors investigate the inhibited oxidation of SKN-18, SKN-26 and SKN-40 butadiene-acrylonitrile rubbers in a micro-oxidation apparatus at various temperatures. 2. It is established that the rate of inhibited oxidation of butadiene-acrylonitrile rubbers is determined by their nitrile group content.

The Modification of Butadiene-Acrylonitrile Rubber with Vinylcyclohexyl Ketone
Rubber Chemistry and Technology, 2002Abstract Butadiene-acrylonitrile-vinylcyclohexyl ketone (BD-AN-VCHK) terpolymer was synthesized by radical polymerization. The structure of the synthesized terpolymer was elucidated by IR spectroscopy and physical and mechanical tests. BD-AN-VCHK terpolymer was stable at lower temperatures and exhibited good adhesive properties.

Hydrogenation of acrylonitrile–butadiene rubber latexes
Journal of Applied Polymer Science, 2003AbstractThe hydrogenation of acrylonitrile–butadiene rubber (NBR) latex was carried out by a system consisting of hydrazine hydrate and hydrogen peroxide, with boric acid as catalyst. Highly saturated hydrogenated NBR (HNBR) latex was obtained through the optimization of the reaction conditions. The dried HNBR was found to be heavily gelled.

Radiation Crosslinking of Acrylonitrile-Butadiene Rubber
2015Radiation modification of polymer materials has been gaining increasing popularity, not only in academic research, but also in industrial applications [1]. Among numerous advantages of radiation modification method, the noteworthy issue is the simplicity to control the ionizing radiation dose, which is absorbed by the modified material, dose rate ...

Polyacrylonitrile determination in acrylonitrile‐butadiene rubber
Journal of Applied Polymer Science, 1997Acrylonitrile content from copolymer of acrylonitrile-butadiene has been studied combining vibrational spectroscopy and a nuclear technique. On the basis of the results obtained, it has been proven that these techniques can clearly be an asset to determine acrylonitrile content in rubber materials without prior separation and in a nondestructive fast ...

Reaction of ozone with natural hevea and acrylonitrile‐butadiene rubbers
Journal of Polymer Science, 1956AbstractThe physical changes that occur when ozone reacts with unvulcanized rubber or unstretched vulcanizates have been studied. The speed of reaction is controlled by diffusion of gas into the rubber; as a consequence, initial products formed near the surface are subjected to further action by ozone. To minimize this possibility experiments have been

AbstractNanocomposites were prepared with different grades of nitrile rubber with acrylonitrile contents of 19, 34, and 50%, with styrene–butadiene rubber (23% styrene content), and with polybutadiene rubber with Na‐montmorillonite clay. The clay was modified with stearyl amine and was characterized by X‐ray diffraction (XRD), Fourier transform ...
