I found the field of Polymer Science very interesting. Saw the article Synthesis and characterization of new cardo poly(ether amide)s containing 9(10H)-anthrone units published in 2020. Formula: C14H10O, Reprint Addresses Wang, QY; Sheng, SR (corresponding author), Jiangxi Normal Univ, Minist Educ, Key Lab Funct Small Organ Mol, Nanchang 330022, Jiangxi, Peoples R China.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone
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%.
