Ionomeric polyblends of zinc oxide neutralized carboxylated nitrile rubber, abbreviated as Zn-XNBR and zinc oxide neutralized poly(ethylene-co-acrylic acid), abbreviated as Zn-PEA, were prepared in the compositions ranging from 90/10 to 50/50, in parts by weight. Out of these blends, compositions of 90/10, 80/20 and 70/30, in parts by weight, behave as ionic thermoplastic elastomers. While synergism...
Interactions of carbon black with nitrile rubber (NBR) and carboxylated nitrile rubber (XNBR) were studied by measurements of bound rubber, physical and dynamic mechanical properties of the vulcanizates and Monsanto rheometric studies on the rubber-filler mixes. Compared with NBR, XNBR shows a higher degree of interaction with the filler and oxidation of the filler surface increases the extent of...
