Non‐equilibrium kinetically frozen structures were observed in weakly charged polyacrylamide gels immersed in a poor‐solvent. These structures are due to the vitrification of polymer‐rich regions inside the gel which appear during the gel collapse. The paper presents the main results of the study of these structures by electron microscopy, SAXS and mechanical measurements.
