In this article, boric acid-modified poly(aryl ether sulfone) (PES-B) membranes were prepared by solution blending, solution casting, evaporation, and programmed temperature curing method for the first time. The chemical modification of poly(aryl ether sulfone) was accomplished by the curing of poly(aryl ether sulfone) with pendent phenyl hydroxide (PES-OH) under the function of boric acid. The reaction mechanisms and the effects of boric acid content were thoroughly investigated. Processing conditions and structures of PES-B were determined by FT-IR spectra. It has been found that the B(OH) 3 /PES composite membranes were completely cured after treatment at 300 C for 4 h. When boric acid content was over 4.7%, PES-B membranes presented phase separation and full cross-linking structures. DSC measurements demonstrated that the addition of boric acid had influenced the glass transition temperature of PES-B, which provided the proof of the appearance of cross-linking network structure. TGA results confirmed that the thermal stability of the prepared PES-B composites was improved. Furthermore, the cross-linked composite membranes exhibited excellent mechanical property and solvent resistance.

“…The frequencies in the 1260-1190 cm À1 region may be attributed to vibrations involving the aryl-ether linkages. [16][17][18][19][20] Two distinct bands, observed at approximately 1330 and 1340 cm À1 , respectively, along with several bands in the 1600-1590 cm À1 region are attributed to the aromatic C-N stretching linkage. The bands in the region of 1490-1400 cm À1 are attributed to the skeletal ring-stretching vibrations of the aromatic and heteroaromatic rings.…”

Eight polycyanurates have been synthesized by the interfacial polycondensation of 2-carbazol-4,6-dichloro-s-triazine with 1,7-dihydroxynaphthalene (DHN-1,7), 1,4-dihydroxyanthraquinone (DHA-1,4), ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), 1,2-propanediol (Pr-1,2), 1,4-butanediol (Bu-1,4) and 1,8-dihydroxyanthraquinone (DHA-1,8). All of the polycyanurates thus synthesized were characterized for their solubility, density, viscosity, infrared spectra, nuclear magnetic resonance spectra and thermogravimetric analysis. Chlorinated solvents were found to be good solvents for all of the polymers. The density of the polycyanurates varied from 1.186 to 1.247 gm cm À3 . The intrinsic viscosity of the polycyanurates followed the sequence given below: homopolycyanurates of DHN-1,7 (HPDHN-1,7)4homopolycyanurates of DHA-1,8 (HPDHA-1,8)4homopolycyanurates of DHA-1,4 (HPDHA-1,4)4homopolycyanurates of EG (HPEG)4homopolycyanurates of DEG (HPDEG)4homopolycyanurates of TEG (HPTEG)4homopolycyanurates of Bu-1,4 (HPBu-1,4)4homopolycyanurates of Pr-1,2 (HPPr-1,2). The thermal stability of the polycyanurates increased as follows: HPTEGoHPPr-1,2oHPDEGEHPBu-1,4oHPEGoHPDHA-1,8oHPDHA-1,4oHPDHN-1,7.
