Synthesis and characterization of poly(aryl ether ketone) oligomers terminated with metallophthalocyanine to be used for oxidative decomposition of TCP



A series of metallophthalocyanine-terminated poly(aryl ether ketone) oligomers were synthesized from dicyanobenzene-terminated poly(aryl ether ketone) oligomers with different metal chloride and phthalonitrile. All polymers exhibited high glass transition temperature and good thermal stability. These polymers showed optical absorption in the visible region and had different colors in chloroform solution. Cobalt phthalocyanine-terminated poly(aryl ether ketone) oligomers exhibited good catalytic activity in oxidative decomposition of 2,4,6-trichlorophenol (TCP) under H2O2 and KHSO5. The catalytic activity of KHSO5 is much better than H2O2, and more than 70% of initial TCP was decomposed within 7 h. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
