โฆ Synopsis
A novel class of copolyesters containing the metallophthalocyanine ring [ M - Pc , M = Fe ( III ), Co ( II )] in the chain was synthesized by polycondensation of (dicarboxyphthalocyaninato) metal [ M - Dapc , M = Fe ( III ), Co ( II )] diacid chloride, terephthalic acid chloride and aliphatic diols. The structures of the copolyesters were characterized by infrared, electronic as well as ESR spectra, and viscosity measurement. The thermal stabilities of the polymers were evaluated by dynamic thermogravimetric analyses. The polymers obtained thus were easily soluble in chloroform, dichloromethane, etc. The green or blue colored fiber was formed by melt spinning of the copolyesters containing below 1 mol % M - Pc component. The copolyester containing Co ( II )- Pc in the chain obtained from 1,2-ethanediol as a diol component catalysed the autoxidation of 2-mercaptoethanol in the presence of oxygen.
