Abstract
Monsanto rheometry, melt viscometry, differential scanning calorimetry , and dynamic mechanical spectroscopy have been used to study the effe cts of zinc stearate on the rheological behavior of ionomer based on c arboxylated nitrile rubber (XNBR) - zinc oxide (ZnO) system. At temper atures below its melting point, zinc stearate functions asa reinforcin g agent for ionomer formation. Above its melting point, it acts as a p lasticizer for the ionic domains, thereby facilitating easy processing of the ionomer.
