ʷ The change of crystalline structure and mechanical properties of i-PP films which had before isothermally annealed at various temperature and times have been studied. The following results were abtain The crystallinity and crystallite size of the samples showed increasing above the annealing temperature of 13 and these are equilibrated after an annealing time of 30min. When the crystalline form was at annealling condition were below 13, 2min, subsequently achieving an , mixing form and at 13, 10min, the crystalline form entered an form transition. It is achieved a typical form at 15. The value of T\'m was increasing until 13 but it was not founded at 15. The slopes which represented crystalline form in an Avrami plot differed from each other within the range of this experiment.
