events. Cylindrical dendronized polymers orient along the length of a fiber when
drawn or extruded, so that stretching and contractions of the helix also occurs along
the length of the fiber. Without the high degree of orientation, the anisotropic
extension that occurs as the helix unwinds would not be expressed as macroscopic
movement and a directional force.
