Abstract
The defects of the worm texture of a nematic liquid crystalline polyme r are studied by scanning electron microscopy. The observed surfaces a re first prepared by ultramicrotoming, then etched with acid or reveal ed by polyethylene vaporization. The preliminary observations reveal t he existence of half-integer twist disclination loops lying inside the shearing plane.
