Preparation and Characterization of a Novel Hyperbranched Poly(aryl ether ketone) Terminated with Cobalt Phthalocyanine to be Used for Oxidative Decomposition of 2,4,6-Trichlorophenol
E-mail:
A novel hyperbranched poly(aryl ether ketone) terminated with cobalt phthalocyanine (CoPc-T-HPAEK) was prepared using 1,3,5-tris[4-(4-fluorobenzoyl) phenoxy] benzene (B3), as a ‘core’ molecule, 4,4'-(hexafluoroisopropylidene) diphenol (6F-BPA) as an A2 monomer, and cobalt phthalocyanine as an end-capping reagent. CoPc-THPAEK showed good solubility, thermal stability and catalytic activity in the oxidative decomposition of 2,4,6-trichlorophenol (TCP) under H2O2 or KHSO5. Moreover, the oxidative effect of KHSO5 was superior to that of H2O2, and the catalytic activity of CoPc-T-HPAEK was much higher than that of linear poly(aryl ether ketone) terminated with cobalt phthalocyanine (CoPc-T-LPAEK) and linear poly(aryl ether ketone) with a cobalt phthalocyanine pendant unit (CoPc-S-LPAEK).
