Ionomeric blends. II. Compatibility and dynamic mechanical properties of sulfonated cis‐1,4‐polyisoprenes and styrene/4‐ vinylpyridine copolymer blends

摘要: Dynamic mechanical and optical transparency methods were used to investigate the compatibility of a series blends sulfonated cis-1,4-polyisoprene styrene/4-vinylpyridine copolymers. It was found that compatibilization occurs at degree substitution less than 5%. is suggested proton transfer from sulfonic acid group vinyl pyridine, which results in generation specific anion-cation interactions, responsible for compatibilization, since removal ionic interactions through esterification destroys compatibility.
