| Abstract: | Abstract New copolyether sulfones containing 2,5-bis(4-oxo-benzylidene)-cyclopentanone moieties were prepared in the conventional literature manner by condensing the dipotassium salts of 2,5-bis(4-hydroxyphenzyl- idene)cyclopentanone (I) and 2, 2-bis(4-hydroxyphenyl)propane (Bisphenol A, III) with 4,4′-dichlorodiphenyl sulfone (II), or by condensing the dipotassium salts of I with chlorine-terminated Bisphenol A-4,4′-di-chlorodiphenylsulfone copolymers (V). The resulting copolyether sulfones were confirmed by IR, viscometry, DSC measurements, thermooptical (TOA), and thermogravimetric analysis (TGA). |
