Study on unusual spherulites of PET and PBT by small-angle laser scattering
PET and PBT can grow into usual or unusual spherulites respectively when they are annealed or quenched. In this paper, the conditions of formation of unusual spherulites and their scattering patterns are investigated by smallangle laser scattering. By means of the model of effective dipole moment and Fourier transform principle, the formation causes of the scattering patterns are analysed and the internal structure of the unusual spherulites is illustrated.
