Abstract
Low-molecular compounds present in the melt of isotactic polypropylene in concentrations exceeding a certain limit, transform some elements of disordered domains into additional sorption centers for the same compounds. These centers can persist after the removal of the low-molecular compound leading to a post-plasticizing effect. This effect slowly disappears at elevated temperatures (80-100°C). The theory of sorption centers rearrangement is discussed.Keywords
