Interrelations between processing, orientation and shrinkage in low density polyethylene blown films. II. Orientation of the crystalline phase.

International audienceIn this second paper, the orientation of the crystalline phase is characterized by three methods : Debye-Scherrer diagrams, pole figures and orientation functions. We try on the one hand to establish correlations between orientation and processing conditions, and on the other hand to interpret our experimental results using morphological model
