New Copoly(bisphenol‐A)carbonates, Having Hydrophilic Porphyrin Units as End‐Groups, Synthesized by Melt‐Reacting Processes

Abstract

The synthesis of some poly(bisphenol‐A)carbonates (PCs) containing hydrophilic porphyrin units as end groups, by thermal treatment of commercial PC and 5,10,15‐tri{p[ω‐methoxy‐poly(oxyethylene)]phenyl}20(p‐hydroxy phenyl)porphyrin (I) 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.
