Preparation and characterization of cross-linked polymer supports for catalysts immobilization

A series of macroporous cross-linked polystyrenes for applications as supports in catalysis have been synthesized and characterized in terms of their structural, thermal and morphological features. In this regards, we have shown how Fourier-transformed infrared spectroscopy mapping (μ-FTIR) may represent a very useful and easy-to-handle tool for the advanced spatial characterization of substituted cross-linked resins at a single bead level, thereby helping synthetic chemists in the prediction of their behavior during chemical processes. Further, scanning electron microscopy (SEM), thermal analysis (MTDSC), and N2 absorption (BET) measurements have been performed. Direct correlations between the polymerization conditions and resins chemical-physical properties have been identified.
