New copoly(bisphenol-A)carbonates, having hydrophilic porphyrin units as end-groups, synthesized by melt-reacting processes

The synthesis of some poly(bisphenol-A)carbonates (PCs) contg. hydrophilic porphyrin units as end groups, by thermal treatment of commercial PC and 5,10,15-tri {p[?-methoxy-poly(oxyethylene)]phenyl}20(p-hydroxy phenyl)porphyrin (1) blends, is reported. A suitable choice of reaction temperature, molar composition and reaction time, allowing the extent of the outer-inner transesterification reactions, leads to a gradual insertion of porphyrin units in the polymer chains. The composition of the obtained materials was inferred by GPC and MALDI-TOF mass spectrometric analysis.
