Abstract
Several new cardopolyamides containing phenoxathiin-10,10-dioxide and phenoxaphosphine units were prepared by condensing 3,3-bis(4-aminophenyl)-phthalide (PDA), 9,9-bis(4-aminophenyl) fluorene (FDA), and 9,9-bis(4-aminophenyl)-10-anthrone (ADA) with 2,8-dichloroformylphenoxathiin-10,10-dioxide (PDC) and 2,8-dichloroformyl-10-phenylphenoxaphosphine-10-oxide (PPDC) in DMAc. A low temperature solution polycondensation technique was employed throughout. The cardopolymides were obtained in 80–92% yield and showed inherent viscosities in the range 0.41–0.6 dL/g. All the polymers were characterized by IR spectra, density, solubility, crystallinity, and thermal analysis.
