**Abstract**
 A series of polyetherimides was prepared by nucleophilic displacement reaction of bisnitrophthalimides containing ether and sulphur linkages with aromatic diols in dimethyl sulphoxide. The two new bisnitrophthalimides, 4,4'-bis(Nphenoxy4-nitrophthaliimide)-2,2'-diphenylisopropylidene and 4,4'-bis(N-phenoxy-4-nitrophthalimide)diphenylsulphide were prepared from the corresponding diamines and 4-nitrophthalic anhydride. The nitro displacement polymerisation yielded high molecular weight polyetherimides with inherent viscosities of 0.460.54 dL/g. The polyetherimides were soluble in dipolar aprotic solvents such as DMSO, DMF and NMP. These polymers had glass transition temperatures around 200 degrees C. Thermogravimetric analysis indicated that the 10% weight loss temperature for these polymers ranged from 430 to 490 degrees C with a high char yield at 800 degrees C. 18 Refs.
