Transition of ionic clusters in ionomers

Differential scanning calorimetric and thermal expansion measurements were made for the complex Zn(II) salts of ethylene-methacrylic acid copolymer with 1, 3-bis-aminomethylcyclohexane. One transition of the ionic clusters in the polymer matrix was found near 325 K as a peak on the DSC and thermal e...

Description
Summary:Differential scanning calorimetric and thermal expansion measurements were made for the complex Zn(II) salts of ethylene-methacrylic acid copolymer with 1, 3-bis-aminomethylcyclohexane. One transition of the ionic clusters in the polymer matrix was found near 325 K as a peak on the DSC and thermal expansion curves. The transition exhibited a thermal hysteresis which was explained by the relaxational destruction/reformation of a structure in the inside of ionic clusters.
