SOLUTION OF THE POLYMER MSA FOR THE POLYMERIZING PRIMITIVE MODEL OF ELECTROLYTES

An analytical solution of the polymer MSA (mean spherical approximatio n) for the polymerizing primitive model of electrolytes is obtained. T he approximation is an extension of the associative MSA proposed recen tly [M. Holovko and Yu. Kalyuzhnyi, Mel. Phys. 73 (1991) 1145] to stud y the effects of association in ionic systems. The model is defined by adding charges to the totally flexible sticky two-point model of asso ciating monomers introduced by Wertheim. In the limiting case of an un charged system, our solution reduces to the solution of the Wertheim p olymer PY approximation solved recently [J. Chang and S.I. Sandler, J. Chem. Phys. 102 (1995) 437].
