Abstract:  The influence of the molecular weight distribution of polymers on liquid —liquid phase relationships is investigated theoretically and illustrated with experimental examples. The polydispersity reveals itself in an identical way irrespective of the kind of system considered. Various types are discussed: solvent—polymer; solvent—polymer 1—polymer 2; polymer 1—polymer 2; solvent—non solvent—polymer. In none of these cases is it permitted to consider the polymeric constituent(s) as a single component. Methods are described to account quantitatively for polydispersity. The efficiency of polymer fractionation is briefly commented upon.
