Abstract
The criteria of polymer-polymer miscibility determined by dilute-solution v iscometry are reviewed and this method was applied to study blend systems o f rigid-rod (or semi-rigid) polymers and flexible polymer. The interactions of poly(benzazole) family (short as PBZs) with nylon 66 were investigated in methanesulfonic acid using dilute-solution viscometry (DSV) criteria and differential scanning calorimetry. Then the DSV data were analyzed by seve ral different criteria reported previously to find out which criterion is m ore efficient and reasonable; moreover, the miscibility of the PBZs and nyl on 66 was studied in detail. It was observed that PBO molecules have the st rongest interaction force with nylon 66 molecules in the four blend systems presented in this paper. (C) 2000 Elsevier Science Ltd. All rights reserve d.
