Popis:	Blends of the polyimides based on the dianhydrides O(CO) 2 Ph(CO) 2 O, O(CO) 2 Ph-R-Ph(CO) 2 O (R=−, CO, O, C(CF 3 ) 2 ) and on the para- and meta-substituted diamines H 2 NPh-CMe 2 PhNH 2 are studied. The results show that these polyimides are missible with each other if: (1) the dianhydride composition is the same in each pair, and (2) the diamine is changed from the meta-diamine to the para-diamine. These results are consistent with calculations based on the Flory-Huggins theory
