Styrenic DABCO salt-containing monomers for the synthesis of novel charged polymers

Abstract

A facile, two-step synthesis afforded styrenic DABCO salt monomers bearing two cyclic quaternary ammonium cations. Free radical polymerization of the DABCO salt monomers yielded homopolymers and copolymers with n-butyl acrylate. DABCO salt-containing ionomers exhibited superior thermomechanical properties with extended plateau regimes compared to ionomers bearing singly-charged pendant groups.
