摘要
The ionic elastomer based on the carboxylated nitrile rubber (XNBR)-zinc oxide (ZnO) system shows a biphasic transition. It is believed that the low temperature transition around - 5 degrees C is due to the main chain glass-rubber transition and the high temperature transition around + 55 degrees C is due to the formation of ionic clusters. Incorporation of reinforcing carbon black fillers makes the high temperature transition more prominent and it is also shifted to a higher temperature. Formation of ionic clusters in XNBR-ZnO system is believed to cause high rubber-filler interaction and striking changes in storage modulus, loss modulus and loss tangent at different dynamic strain amplitudes, as compared to the XNBR crosslinked by sulfur-accelerator system.
