Rheological properties of the ionomeric polyblends of zinc salts of maleated ethylene propylene diene monomer (EPDM) rubber and poly(ethylene‐ co ‐acrylic acid) were studied using a Monsanto Processability Tester. The ionomeric polyblend exhibits higher melt viscosity than the corresponding nonionomeric polyblend. Besides reduction in the melt viscosity of the ionomeric polyblend, zinc stearate increases the tensile strength and elongation at break of the ionomeric polyblend. Reprocessability studies reveal the thermoplastic elastomeric nature of the blend. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 71: 1257–1265, 1999
