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[omega-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 10 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.File in questo prodotto:
