Aggregation behavior of halato-telechelic ionomers in a low-polarity solvent

Summary The solution behavior of halato-telechelic ionomers (polybutadiene with carboxylate end groups) in a low-polarity solvent (tetrahydrofuran (THF)) was studied. It was shown that the degree of aggregation can be expressed as a function of polymer concentration by an empirical equation, DA - 10_c, where DA is the degree of aggregation, c is polymer concentration, and is a constant relating to the rate of aggregation with polymer concentration. It was also shown that the aggregation effect of the Na salt was larger than that of the Cs salt, which was reflected in the value of .
