摘要：

Complex coacervation is explained with the assumption that the symmetrical aggregate polymer (SAP) model is applicable to both dilute and concentrated phases. An interaction potential between SAP's is obtained in a way similar to the derivation of the Flory-Krigbaum potential between usual polymers. Using this potential, osmotic pressure P is obtained by the virial expansion method. The curve of P (vs volume fraction of SAP) corresponds to the curve of pressure (vs volume) representing gas-liquid phase separation. Moreover the self-suppression is quantitatively explained by the contraction of SAP dimension. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
