Polymers for use as an Anion Exchange Membranes (AEMs) and produce an alkaline stable AEM. The multinuclear aromatic and amine-functionalized acetal (ketal) come together to form a polymer with a hydrocarbon backbone that is stable to alkaline conditions. The use of an amine-functionalized acetal allows for the incorporation of a stable cation, dimethyl piperidinium, in the most stable confirmation while avoiding incorporation of a CF3 group with every cation. The amines within the amine-functionalized polyaromatic that results from this polymerization are quaternized to form the desired cationic groups to create an AEM that is mechanically robust, conductive, and stable.
