Abstract
Acid-base interactions can be used to overcome the free energy barrier to t he mixing of rods and coils, originating primarily from the reduced entropy of the coil conformation in the presence of rods. A study of rigid-rod pol ydiacetylene, carrying pyridine side groups, and sulfonated polystyrene ble nds, in conjunction with a modified Flory theory, shows a rich variety of o bserved and expected phase behavior.
