| Abstract: | A series of poly(aryl ether sulfone ketone)s containing phthalazinone and biphenyl moieties were synthesized by aromatic nucleophilic displacement polycondensation of 4-(4-hydroxylphenyl)(2H)-phthalazin-1-one(DHPZ),4,4'- dichlorobenzophenone(DCB),4,4'-dichlorodiphenyl sulfone(DCS) and 4,4'-biphenol(BP) in different molar ratios.The obtained copolymers were characterized by different instrumental techniques(FTIR,TGA,DSC,WAXD,etc.).The inherent viscosities of these polymers were in the range of 0.43-0.56 dL g... |
