A bis(ether anhydride) monomer, 1,1-bis [4-(3,4-dicarboxyphenoxy)phenyl-]cyclohexane dianhydride (IV-A), was synthesized from the nitro displacement of 4-nitrophthalodinitrile by the phenoxide ion of 1,1-bis(4-hydroxyphenyl)cyclohexane (I-A), followed by alkaline hydrolysis of the intermediate bis(ether dinitrile) and dehydration of the resulting bis(ether acid). A novel series of organosoluble poly(ether imide)s (VI a-i )(PEIs) bearing cyclohexylidene cardo groups was prepared from the bis(ether anhydride) IV-A with various aromatic diamines V a-i via a conventional two-stage process. The PEIs had inherent viscosities in the range of 0.48 -1.02 dL/g and afforded flexible and tough films by solution-casting because of their good solubilities in organic solvents. Most PEIs showed yield points in the range of 89 -102 MPa at stress-strain curves and had tensile strengths of 78 -103 MPa, elongations at breaks of 8 -62%, and initial moduli of 1.8 -2.2 GPa. The glass-transition temperatures (T g 's) of these PEIs were recorded between 200 -234°C. Decomposition temperatures of 10% weight loss all occurred above 490°C in both air and nitrogen atmospheres, and their residues were more than 43% at 800°C in nitrogen atmosphere. The cyclohexane cardo-based PEIs exhibited relatively higher T g 's, better solubilities in organic solvents, and better tensile properties as compared with the corresponding Ultem PEI system.
