✦ Synopsis

A~tract--Styrene-based ionomers containing the sodium salts of acrylic acid have been investigated by differential scanning calorimetry, far-i.r, spectroscopy and optical microscopy. A study has been made of the influence of the content of the sodium acrylate in the styrene-based ionomers on the state of ions aggregation. It seems that, at low sodium acrylate content, the ions aggregate into multiplets but clusters are formed as the concentration of sodium acrylate is increased.
