Abstract
Complexation abilities and the conformations of the complexes among different polymer chains are controlled by the structure of the component polymer chains. In the case of the combination of a strong and a weak polyelectrolyte, the composition of a complex in a unit molar ratio is determined mainly by the dissociation state of the weak polyelectrolyte which is presumably comparable to its conformation. The conformation of the complex (in this case, the conformational change is estimated from the stability change of the α-helical structure of poly(L-glutamic acid)) varies with the structure of the component polycations, for example, positions of active sites (pendant or integral type), distance between adjacent ionic sites, rigidity, hydrophobicity, and so on.
