Sažetak
New development in EPR techniques hane in recent years significantly expanded the application of EPR in chemistry and related fields. New methods, which have the possibility to detect slow-motional dynamics in the millisecond region, are described here: saturation transfer (CW)-EPR, pulse methods ((SR)-EPR and (SR)-ELDOR), and nonlinear methods (DMEPR and LODEPR). The application ofthese methods to polymer research, with a spetial emphasis on the study of molecular dynamics, relaxation processes and polymer morphology by the DMEPR method, is rewieved in the paper.
