Abstract
Standard density functional approximations greatly overestimate the static polarizability of long-chain polymers, but Hartree-Fock or exact exchange calculations do not. We show that simple self-interaction corrected approximations afford a viable alternative for accurate polarizability calculations within density functional theory.
