ABSTRACT
New homo and copolyether sulfones containing cycloaliphatic cardo groups were prepared in the conventional literature manner by condensing the dipotassium salts of 1, 1-bis(p-hydroxy-phenyl)cyclo-pentane (I a), l, l-bis(p-hydroxyphenyl)cyclohexane (I b), l, l-bis(p-hydroxyphenyl)cycloheptane (I c), and 2, 2-bis(p-hydroxy-phenyl)-propane (Bisphenol A, III) with 4,4′-sulfonyl bis(4-chloro-phenyl) (II). The polymers were characterized by IR 1H-NMR spectres-copy, elemental analysis, viscometry, solubility tests, softening points, DSC and TGA measurements.
