In the current study we focus on the specific polymerizations called as ATRP, which is a type of controlled radical polymerization. One of the aims is to consider the investigation of reaction conversion by gas chromatography and NIR spectroscopy. Generally, NMR is used for following the conversion, however this method is expensive and not widely accessible. In addition it is much more difficult to use it in case of gels and crosslinked materials, which are also prepared by mentioned polymerization methods. Gas chromatography allows analyzing unreacted monomer(s) and thus gain conversion, the aim is to investigate the possibilities of the workup of reaction mixture for analyses. NIR spectroscopy is a method allowing continuous online following of reaction mixture by a probe. I tis only a marginal method nowadays. Following aim is a detailed study of molecular-weight characteristics of linear polymers and analysis of polymer gels and networks by spectroscopy (e.g. FTIR) and other methods like gravimetric or mechanic. Gained knowledge will be used in applications of specialty polymerizations and tuning of syntheses of polymers and copolymers.
