Simplified mean field theory for the phase behaviour of polyelectrolytes in solution is described in detail. It can be viewed as the polyelectrolyte analogue of Flory-Huggins theory. A basic nlodel is analyzed, then extended to look at the effects of multivalent ions (specifically divalent coions), of distinguishable counterions, and of an ionization equilibriunl between counterions and polyele...

The pressure dependence of the Flory Huggins interaction parameter of two binary polymer blends was investigated by small angle neutron scattering (SANS). We studied the polymer blends deutero PoIystyrene / Polyvinylmethylether (d PS / PVME) and deutero Polystyrene / Polyphenylmethylsiloxane (d PS / PPMS), exhibiting decomposition at high and at low temperatures, respectiveIy. In both cases the...

The occurrence of gelation and the existence of mass-conserving solutions to the continuous coagulation-fragmentation equation are investigated under various assumptions on the coagulation and fragmentation rates, thereby completing the already known results. A non-uniqueness result is also established and a connection to the modified coagulation model of Flory is also made.
