Abstract

Correlation function analysis on the SAXS profiles for ionomers containing alkali metals based on copolymers of styrene-acrylic acid and styrene-methacrylic acid obtained in emulsion are presented. The analysis was performed based on the liquid-like model of ionomer structure introduced by Yarusso and Cooper. A study has been made on the influence of content, type of salt and type of alkali metal in styrene- based ionomers on the state of ion aggregation. In all cases the state of ion aggregation is independent on the content of introduced acrylate or methacrylate and is dependent type of introduced alkali metal. The obtained results indicate that in the case of ionomers containing cesium acrylate aggregates of larger sizes are formed than containing cesium methacrylate. For all investigated ionomers the increase of temperature causes the increase of sizes and volume fraction of clusters.
