  A living polymers transition is found in molecular dynamics simulations of a
charge-symmetric size-asymmetric electrolyte with no anisotropic interactions.
The fluid has strong polymeric character at low temperatures, where it consists
of large, alternating-charge linear chains and rings in chemical equilibrium. A
mean-field theory of chain association is consistent with the existence of such
a transition. In the polymeric phase the system is very weakly conducting or
electrically insulating.
