## Abstract A highly ionic conductive solid‐gel membrane based on polyacrylamide hydrogels with a K~2~CO~3~ additive was investigated. The polymer‐based gel was prepared by adding ionic species K~2~CO~3~ to a monomer solution followed by polymerization. After polymerization, the ionic species was e

The Na 2 CO 3 -promoted polymerization of 1,3-dioxolan-2-one (I) to afford poly(ethylene glycol) III was reinvestigated. The reaction appeared to involve a nucleophilic attack against the carbonyl and methylene groups of I to afford poly(carbonate) II with poly(ethylene glycol) linkages and ethylene
