Query: Phase diagram of diblock polyampholyte solutions   We discuss in this paper the phase diagram of a diblock polyampholyte
solution in the limit of high ionic strength as a function of concentration and
charge asymmetry. This system is shown to be very similar to solutions of
so-called charged-neutral diblock copolymers: at zero charge asymmetry the
solution phase separates into a polyelectrolyte complex and almost pure
solvent. Above a charge asymmetry threshold, the copolymers are soluble as
finite size aggregates. Scaling laws of the aggregates radius as a function of
pH of the solution are in qualitative agreement with experiments.
