  We present simulations on charged polymers in poor solvent. First we
investigate in detail the dilute concentration range with and without imposed
extension constraints. The resulting necklace polymer conformations are
analyzed in detail. We find strong fluctuations in the number of pearls and
their sizes leading only to small signatures in the form factor and the
force-extension relation. The scaling of the peak in the structure factor with
the monomer density shows a pertinent different behavior from good solvent
chains.
