Magnetically active response of acrylonitrile-butadiene-rubber-based magnetorheological elastomers with different types of iron fillers and their hybrid

, 2021
In this study, two types, namely carbonyl and electrolytic iron particles with different filler structures, and their hybrid (1:1 ratio) were investigated for the magnetically active responsive properties in acrylonitrile butadiene rubber (NBR)-based ...

Towards a tough reprocessable and self-healable acrylonitrile-butadiene rubber based on strong hydrogen bonding interactions

, 2021
Irreversible crosslinking of covalently cross-linked rubber makes it possible to achieve outstanding mechanical properties as well as chemical resistance but makes its reprocessing impossible, which causes great waste of resources and environmental ...

Comparison properties of natural rubber/virgin acrylonitrile–butadiene rubber and natural rubber/recycled acrylonitrile–butadiene rubber blends

Iranian Polymer Journal, 2015
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 ...

Hydrogenation of acrylonitrile–butadiene rubber latexes

Journal of Applied Polymer Science, 2003
AbstractThe 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

2015
Radiation 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, 1997
Acrylonitrile 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, 1956
AbstractThe 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

ACRYLONITRILE–BUTADIENE RUBBER STABILIZED BY METHACRYLAMIDES AS ANTIOXIDANTS

Polymer-Plastics Technology and Engineering, 2000
Methacryloyl chloride was reacted with 4-amino and 4-thiophenols to provide the corresponding methacrylamides. These compounds were incorporated in NBR mixes to be evaluated as antioxidants for NBR oil-seal products in comparison with the industrial antioxidant phenyl-B-naphthylamine (PBN).

Ground rubber/acrylonitrile–butadiene–styrene composites

Composites Science and Technology, 2007
Abstract A range of ground rubber (GR)/acrylonitrile–butadiene–styrene (ABS) composites were developed that contained untreated and various treated rubber particles. The tensile properties of the composite materials were significantly improved over the untreated GR/ABS sample either by a two-step treatment process involving surface chlorination of ...
