Theorem of Corresponding States for Polymer Mixtures

We now consider mixtures of Na molecules A occupying sites of the quasi lattice and characterized by Sc i external degrees of freedom with Nb molecules B diaracterized by ra and 3cb. The intermolecolar eneigies between the elements of A and B are represented by the two parameter interaction law (2.4.2) 

The distances ua and aa are taken to be almost equal in order to preserve the quasi-lattice. 

Using these average potential constants we all now generalize the theorem of corresponding states developed in Ch. XVI, 7 to include the case of polsrmer mixtures. 

First of all, the straightforward generalization of the expresaon (16.7.6) for the configurational partition function to the case of mixtures is 

As for pure r-mer s we shall now assume that the cell partition function per external degree of freedom depends only on the reduced volume. Again lye could also use the less restrictive assumption (16.7.13) as long as we are concerned only with the equation of state.
