Derivatization of synthetic polymers in mass spectrometric studies

The review describes various derivatization approaches employed for the investigation of synthetic polymers by mild ionization mass spectrometry (fast atom and ion bombardment, matrix-assisted laser desorption/ionization, electrospray/ionization). The potentials of chemical methods for modification of end- and side-chain functional groups without the decomposition of molecules are demonstrated. Methods of the preliminary chemical degradation of polymer molecules for the investigation of their microstructure are considered. The possibilities of the chemical modification of polymer surfaces for the identification and quantitative determination of functionalized fragments are shown.
