β¦ Synopsis
Novel poly(arylene ether)s were synthesized from new biphenol monomers 14 -16 1 containing imido-or dicyanoarylene groups. The syntheses of these polymers were carried out in tetramethylene sulfone in the presence of anhydrous K 2 CO 3, by a nucleophilic substitution condensation between the biphenol and activated difluoro compounds to give high molecular weight polymers. All the polymers have high T g 's and good thermal stability as determined from DSC and TGA analysis. Inherent viscosities of these polymers are in the range of 0.33-0.63 dL/g. They are amorphous and readily soluble in NMP, DMF, and DMSO. The glass-transition temperatures of the polymers range from 248 -295 Β°C.

A series of new high molecular weight poly(arylene ether)s containing the 1,2-dihydro-4-phenyl(2H)phthalazinone moiety have been synthesized. The inherent viscosities of these polymers are in the range of 0.33-0.64 dL/g. They are amorphous and readily soluble in chloroform, DMF, and DMAc. The glass
The design and synthesis of novel charge (hole-or electron-) transport materials have been the focus of much research in recent years because of their wide variety of applications. In this study, three high molecular weight poly(arylene ether)s, 6a-c, containing naphthyl-substituted benzidine moieti
In this work we present the results from studies on novel poly(arylene ether ketone)s, including gas permeability, wide-angle x-ray diffraction (WAXD), and dynamic mechanical analysis (DMA). Poly(arylene ether ketone)s containing 2,2and 3,3 -dibenzoylbiphenyl (DBBP) moieties were characterized to st
## Abstract Five new poly(arylene ether)s containing phthalimidine group in the main chain and pendent trifluoromethyl group have been prepared by the reaction of 4,4β²β(bisβ4βfluoroβ3βtrifluoromethylphenyl)benzene (BTF) with bisphenols. Different molar ratios of __N__βphenylβ3,3βbis(4βhydroxyphenyl
