The theoretical treatment of polymers with attractive interactions is
introduced. It is suggested that this unsolved problem is treated by n
ew collective coordinates, such as pair fields, which are sensitive to
pairs of different components of the system. Such pair fields are kno
wn from the BCS theory of superconductivity. Their correlation functio
ns and integral equations show instabilities which correspond to the f
ormation of complexes and/or aggregations. Physical examples for such
considerations are semidilute polyelectrolyte solutions containing opp
ositely charged polyions.
