Abstract
Rheological properties of the ionomeric polyblends of zinc salts of maleate d ethylene propylene diene monomer (EPDM) rubber and poly(ethylene-co-acryl ic acid) were studied using a Monsanto Processability Tester. The ionomeric polyblend exhibits higher melt viscosity than the corresponding nonionomer ic polyblend. Besides reduction in the melt viscosity of the ionomeric poly blend, zinc stearate increases the tensile strength and elongation at break of the ionomeric polyblend. Reprocessability studies reveal the thermoplas tic elastomeric nature of the blend. (C) 1999 John Wiley & Sons, Inc.
