## Abstract Two series of poly(ether imide)s (PEIs) containing fluorenyl cardo groups in the main chains were synthesized, which are derived from the polycondensation of 9,9′‐bis(4‐aminophenoxyphenyl)fluorene (BAOFL) or 9,9′‐bis(3‐trifluoromethyl,4‐aminophenoxyphenyl)fluorene (6F‐BAOFL) with four k
## Abstract Two diamines, 2,6‐bis(4‐aminophenoxy)pyridine and 2,6‐bis(5‐amino‐1‐naphenoxy)pyridine, were prepared through the nucleophilic aromatic substitution reaction of 4‐aminophenol and 5‐amino‐1‐naphthol, respectively, with 2,6‐dichloropyridine. Poly(ether urea)s were synthesized through the
Novel poly(amide imide)s having inherent viscosities in the range 0.89-1.56 dL/g were prepared by the method of low temperature polycondensation in solution of N,N-dimethylacetamide (DMA) from aromatic diamines and a new monomer: N-[4"-(chloroformylphenyl) -4'-iminobenzoyl] trimellitimide chloride.
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
A new adamantane-based bis(ether anhydride), 2,2-bis [4-(3,4-dicarboxyphenoxy)phenyl]adamantane dianhydride, was prepared in three steps starting from nitrodisplacement of 4-nitrophthalonitrile with the potassium phenolate of 2,2-bis(4hydroxyphenyl)adamantane. A series of adamantane-containing poly(
