Polymers may offer a safer alternative to liquid electrolyte supports in lithium ion batteries. We are investigating dicarboximide-functionalized oxanorbornyl homopolymers as potential solid polymer electrolytes. To that end, we have synthesized dicarboximide-functionalized oxanorbornyl polymers with varying ethylene oxide (EO)n side chains with 2, 3, and 4 EO units polymers via a ring opening metathesis reaction under living conditions using a Grubbs third generation catalyst. The polymers were characterized with 1H and 13C NMR as well as GPC. The molecular weights of the polymers are on the order of 36000 g/mol with narrow polydispersities of less than 1.1. Further characterization will include impedance spectroscopy to measure lithium ion mobility, and solid state NMR to measure polymer dynamics.
