Two sulfonyl group-containing bis(ether anhydride)s, 4,4 -[sulfonylbis(1,4-phenylene)dioxy]diphthalic anhydride ( IV ) and 4,4 -[sulfonylbis(2,6-dimethyl-1,4-phenylene)dioxy]diphthalic anhydride (Me-IV ), were prepared in three steps starting from the nucleophilic nitrodisplacement reaction of the b
## Abstract Summary: A series of organosoluble and colorless fluorinated poly(ether imide)s (IV~aβg~) were prepared from 3,6βbis(3,4βdicarboxyphenoxy)benzonorbornane dianhydride (I) and various trifluoromethyl (CF~3~)βsubstituted aromatic bis(ether amine)s II~aβg~ by a standard twoβstep process wit
A novel bis(ether anhydride) monomer, 9,9-bis [4-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride (4), was synthesized from the nitrodisplacement of 4-nitrophthalonitrile by the bisphenoxide ion of 9,9-bis(4-hydroxyphenyl)fluorene (1), followed by alkaline hydrolysis of the intermediate tetranitril
