Abstract : Equations are presented for the scattering of light by twodimensional polymer spherulites in which the optic axes of the uniaxial crystals are oriented at an arbitrary angle B to the radii. For the case where the axes lie in the plane of the disc, the scattering patterns is identical to those calculated previously for B = 0 degrees, except that they are rotated through the azimuthal angle by the amount B. Of special interest is the case where the crystals rotate helicoidally about the radii (banded spherulites). The equations predict scattering maxima whose position is related to the period of rotation and the angle B. (Author)
