Safety of Anthrone. In 2020 HIGH PERFORM POLYM published article about OPTICALLY TRANSPARENT POLYAMIDES; AROMATIC POLYAMIDES; LIGHT COLOR; LINKAGES in [Luo, Yi-Sheng; Wang, Qiu-Ying; Mao, Xue-Chun; Sheng, Shou-Ri] Jiangxi Normal Univ, Minist Educ, Key Lab Funct Small Organ Mol, Nanchang 330022, Jiangxi, Peoples R China in 2020, Cited 25. The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.
A new aromatic diamine, 10,10-bis[4-(4-aminophenoxy)phenyl]-9(10H)-anthrone (BAPA) has been synthesized from anthrone via three-step procedure. Direct phosphorylation polycondensation of BAPA with various aromatic dicarboxylic acids produced a series of cardo poly(ether amide)s with inherent viscosities of 0.97-1.29 dL g(-1). All the polymers were readily soluble in polar solvents such as N-methyl-2-pyrrolidone, N, N-dimethylacetamide (DMAc), and pyridine at room temperature, and afforded transparent, strong, and flexible films upon casting from DMAc solvent. The resulting poly(ether amide)s had glass transition temperatures of 254-316 degrees C, 10% weight loss temperatures of 495-524 degrees C, and char yields of 55-70% at 800 degrees C in nitrogen. These polymers were amorphous and their films exhibited tensile strengths of 81.6-104.7 MPa, tensile moduli of 1.8-2.4 GPa, and elongations at break of 8-15%.
