ABSTRACT:  Dynamic viscoelastic measurements are made on six potassium neutralized telechelic poly(ethylene butylene) ionomer (CTPEB-K) solutions in anhydrous decalin with C from 7 to 70 wt % as well as the bulk sample for establishing viscoelastic properties of this system along with earlier data over the whole concentration range. Differences in the formation process of viscoelastic networks and their structures between the two ionomeric systems of CTPEB-K and -Mg are extensively discussed using concentration dependencies of viscosity and the number density of the elastically effective chains and also the temperature dependence of the shift factor obtained from the time–temperature reduction scheme.
