Abstract: | The dependence of the critical concentration of the ternary system polymer-polymer-solvent on the molecular weight can be expressed by the relation where cc is the critical concentration, M? the appropriate average of the molecular weight of both polymers; A and cc∞ are constants for the given system. The possibility of determining the molecular weight of one of the polymers from the value cc and the molecular weight of the known polymer with the aid of equation (1) is discussed. |
