Abstract

A novel transition temperature in MeAM copolymer microgels is reported. Despite the fact that MeAM homopolymers do not show thermosensitive properties, a specific synthetic strategy leads to a thermo‐responsive swelling behavior that could be potentially useful in medical and/or industrial applications. The pH and temperature‐dependent swelling response of microgels of MeAM copolymerized with 2‐aminomethylpyridine and ethylenediamine is reported. The changes in particle sizes, which depend on the nature of the surrounding environment, are recorded by QELS. The relation between copolymer structure and its novel behavior is analyzed by several techniques (^1^H NMR, TGA).
