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.
