Abstract

The comparison of the melt rheology for randomly functionalized ionomers with different anion type was presented. An excess of concentrated hydrochloric acid was added to a small portion of the ionomer solution to generate the acid derivative for fourier transform infrared (FTIR) immediately after carboxylation. The esterified polymer was precipitated into methanol, redissolved in tetrahydrofuran and reprecipitated into methanol. The results show that the principal peak in the chromatogram remains narrow and shifts very slightly to shorter elution times, reflecting a small increase in hydrodynamic volume upon addition of the ethyl ester groups.
