“…There is no doubt that ideal structure modification of polymer is expected to provide balanced properties of high thermal stability and good processability. It has been demonstrated that PAs bearing bulky cyclic side groups (usually named as cardo groups) such as fluorene, 11 –13 phthalide, 14 tert -butylcyclohexylidene, 15 xanthene, 16,17 or cyclopentylidene 18 can exhibit a significant increase in both glass transition temperature ( T g ) and thermooxidative stability while providing good solubility. The 9(10 H )-anthrone structure as a bulky pendent group was previously incorporated into the polymer backbones of the PAs and polyimides to improve their processability based on 10,10-bis(4-aminophenyl)-9(10 H )-anthrone monomer.…”

10,10-Bis[4-(4-aminophenoxy)-3-methylphenyl]-9(10 H)-anthrone, as a new aromatic diamine, was synthesized from 9(10 H)-anthrone by three-step procedure. Low-temperature polycondensation of this diamine with various aromatic dicarboxylic acid dichlorides produced a series of new cardo poly(ether amide)s with moderate to high inherent viscosities of 0.86–1.43 dL g−1 while the weight-average and number-average molecular weights were in the range of 48,600–59,800 and 29,800–35,600 g mol−1, respectively. All the polymers were readily soluble in polar solvents such as N, N-dimethylacetamide (DMAc), N, N-dimethylformamide, N-methyl-2-pyrrolidinone, dimethyl sulfoxide, and pyridine, and afforded transparent, flexible, and strong films upon casting from DMAc solvent. These polymers had glass transition temperatures of 254–297°C, 10% weight loss temperatures of 493–505°C, and char yields of 61–64% at 800°C in nitrogen. All polymers were amorphous and their films exhibited tensile strength of 80.7–101.4 MPa, elongation at break of 8.0–12.8%, and tensile modulus of 1.9–2.6 GPa. These polymers had low moisture uptake in the range of 2.13–4.02% and high transparency with an ultraviolet–visible absorption cutoff wavelength in the 322–375 nm range.

“…cyclododecylidene, tert -butylcyclohexylidene, tricyclo[5.2.1.0 2,6 ]decane, norbornane, fluorene, and xanthene) along the polymer backbone has been shown to impart greater solubility as well as better mechanical and thermal properties to the resulting PAs. 20 –26 The cardo, anthrone group has been incorporated into the polymer backbones such as PAs and polyimides derived from 10,10-bis(4-aminophenyl)-9( 10H )-anthrone, as well as polyarylates and poly(1,3,4-oxadiazole)s based on 10,10-bis(4-carboxyphenyl)-9( 10H )-anthrone to improve the processability. 27 However, to our knowledge, no work has been done on the fluorinated PA bearing both a flexible ether linkage and a bulky anthrone group in the polymer backbone.…”

A new aromatic diamine, 10,10-bis[4-(4-amino-3-trifluoromethylphenoxy)phenyl]-9( 10H)-anthrone (BATFPA), has been synthesized from anthrone via three-step procedure. Low-temperature polycondensation of BATFPA with various aromatic dicarboxylic acid chlorides produced novel fluorinated polyamides with moderate to high inherent viscosities of 0.75–1.03 dL/g while the weight-average molecular weight and number-average molecular weight were in the range of 66,000–74,000 and 37,000–41,000, respectively. Nearly, all the polymers were readily soluble in polar solvents, such as N,N-dimethyl acetamide (DMAc), N-methyl-2-pyrrolidinone, pyridine, and tetrahydrofuran, and afforded transparent, light-colored, and flexible films upon casting from DMAc solvent. These polymers had glass transition temperatures of 249–309°C, 10% weight loss temperatures of 486–517°C, and char yields of 53–61% at 800°C under nitrogen. All polymers were amorphous and their films exhibited tensile strengths of 64–86 MPa, tensile moduli of 1.8–2.2 GPa, and elongation at break of 10–18%. These polymers had dielectric constants ranging from 3.25 to 3.76 (100 Hz), low moisture uptake in the range of 0.72–1.18%, and high transparency with an ultraviolet–visible absorption cutoff wavelength in the 360–378 nm range.
