The use of NIR-FT-Raman spectroscopy for the characterization of polymer-supported reagents and catalysts

摘要: Abstract The NIR-FT-Raman spectroscopy represents a very useful tool for the qualitative, semiquantitative and quantitative characterization of functional polymers being used preparation resin-supported reagents catalysts. This is clearly complementary to generally obtained using FT-IR techniques. simplicity Raman sampling techniques makes them suitable use with highly crosslinked, insoluble overcomes, many often, limitations raised by presence polar groups. Even some groups such as chloromethyl or thiol are easily analyzed FT-Raman spectroscopy. this technique allows not only analysis moieties present but also appropriate polymeric matrix in polystyrene–divinilbenzene resins.
