AbstractA series of polyimides (PIs) based on 2,3,3',4'-benzophenonetetracarboxylic dianhydride (2,3,3',4'-BTDA) and 3,3',4,4'-BTDA were prepared by the conventional two-step process. The properties of the 2,3,3',4'-BTDA based polyimides were compared with those of polyimides prepared from 3,3',4,4'-BTDA. It was found that PIs from 2,3,3,4'-BTDA have higher glass transition temperature and better solubility without sacrificing their thermal properties. Furthermore the theological properties of PMR-15 type polyimide resins based on 2,3,3',4'-BTDA showed lower melt viscosity and wider melt flow region (flow window) compared with those from 3,3',4,4'-BTDA. The structure-property relations resulted from isomerism were discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
