Abstract: In this paper, Hv light scattering patterns of polyethylene spherulites with; concentric-circle extinction are examined by wide-angle laser scattering instrument. The cause of formation of the wide-angle scattering patterns is ex-plained, and twisted phenomena of lamellae are explored by using the model of effective dipole moment. The theoretical analysis is in agreement with the experimental result.

Key words: Polyethylene, Wide-angle scattering, Model of effective dipole
