Journal ArticleDOI
Influence of surface oxidation of carbon black on its interaction with nitrile rubbers
TL;DR: In this article, the interaction of carbon black with nitrile rubber and carboxylated nitric oxide rubber (XNBR) was studied by measurements of bound rubber, physical and dynamic mechanical properties of the vulcanizates and rheometric studies on the rubber mixes.
Journal ArticleDOI
Interaction between Carboxylated Nitrile Rubber and Precipitated Silica: Role of (3-Aminopropyl)Triethoxysilane
TL;DR: In this article, strong rubber-filler interaction occurs between XNBR and precipitated silica filler during molding, and the coupling agent, namely (3-aminopropyl)triethoxysilane facilitates the formation of rubberfiller bonds at the expense of filler-filer networks, leading to improved dispersion and enhanced degree of crosslinking.
Journal ArticleDOI
Synergism in properties of ionomeric polyblends based on zinc salts of carboxylated nitrile rubber and poly(ethylene-co-acrylic acid)
TL;DR: In this paper, the ionic interaction is more prominent in the Zn-XNBR/Zn-PEA blend ratios of 90/10 and 80/20 compared to the non-ionomeric polyblends.
Journal ArticleDOI
Dynamic mechanical spectroscopic studies on the miscibility of polychloroprene—epoxidized natural rubber blend in presence of carbon black filler
TL;DR: In this paper, the authors studied the phase separation of polychloroprene (CR) and epoxidized natural rubber (ENR) during high temperature molding for a prolonged time and found that the microheterogeneity of the blend with high CR content, as in 70 30 CR/ENR-50, arises due to the furanization of the ENR chain induced by HCl liberated from CR during high-temperature molding.
Journal ArticleDOI
Effect of chemical interaction between surface oxidized carbon black and carboxylated nitrile rubber on dynamic properties
TL;DR: In this paper, it was shown that functional groups of oxidized carbon black chemically react with carboxylated nitrile rubber (XNBR) when heated at high temperature for prolonged time.
