Results of measurements of dynamic mechanical and physical properties of the ionic polymer, based on carboxylated nitrile rubber (XNBR) neutralized by zinc oxide (ZnO), reveal that ammonia works as an ionic plasticizer. Accordingly, the main chain transition is little affected but the high temperature transition due to ionic aggregates, as observed in dynamic mechanical measurements, disappeared after...
Results of dynamic mechanical studies and measurements of physical properties of the ionic polymer based on carboxylated nitrile rubber (XNBR) and zinc oxide (ZnO) reveal that dioctylphthalate (DOP) plasticizes the backbone chain of the polymer, while dimethylsulfoxide (DMSO) plasticizes the hard phase arising from the ionic aggregates. Accordingly, the high-temperature ionic transition in the plot...
