Mechanical properties belong to one of the most important parameter of polymers largely determining many of their application areas. Much research has been devoted to understanding the mechanical properties. Despite these efforts, the deformation process in multi-phase materials is not well understood largely due to the lack of information about phenomena that occur at the molecular and nanometric length scales in different phases during deformation. Solid-state NMR methods offer very high selectivity to different phases/components in multi-phase polymers. Strain-induced phenomena in soft phases are of special interest since NMR is highly sensitive to even minor deformation-induced changes and results obtained are complimentary to those by X-ray studies. A significant number of NMR studies were mainly performed for polymers under a fixed strain and after strain-recovery. After a short review of these studies, the focus will be given to NMR studies described results obtained during deformation.
