Abstract

Electrolyte salts with Mg²⁺ and Al³⁺ Lewis acidic cations demonstrate polymerization of 1,3-dioxolane. The speed and extent of the reaction depends on coordination of the anion with the Mg²⁺ cation catalyst. Weakly coordinating anions such as TFSI⁻ aid faster polymerization while strongly coordinating anions such as ClO₄⁻ hinder the polymerization.
