Architectures of copolymers of ethylene with α-olefinic fluorosulfonates are well controlled by tailoring palladium- or nickel-α-diimine catalysts and polymerization conditions (see scheme). These polymeric acids are shown to be “green” homogenous and heterogeneous super-acid catalysts for industrially important reactions. Their lithium salts exhibit excellent ionic conductivities as well as mechanical properties, and are attractive candidates for use in lithium batteries. (MAO=methylalumoxane)
