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.3370-3374application/pdfen-USCreative Commons Attribution-NonCommercial 3.0 UnportedArticle - RefereedZhang, KerenDrummey, Kevin J.Moon, Nicholas G.Chiang, William D.Long, Timothy E.https://doi.org/10.1039/c6py00426a7201759-9962
