Light scattering of polyethylens spherulites with concentric-circle
In this paper, the light scattering patterns of polyethylene spherulitea with concentric-circle extinction are examined by wide-angle laser scattering instrument. Based on the model of effective dipole moment and by moans of Fourier transform and diffraction grating principle, the causes of pattern formation are analysed and the twisted phenomena of lamellae are further discussed. The theoretical analysis is in agreement with the experimental result.
