A STUDY OF DYNAMIC OPTICAL PROPERTIES OF POLYMERIC SOLIDS.

Abstract

Structural changes accompanying the deformation of crystalline polymers have been studied by the techniques of (a) birefringence, (b) light scattering, (c) x-ray diffraction, and (d) dichroism. These techniques have been utilized for both static and dynamic measurements. They have demonstrated that upon deforming a crystalline polymer, the initial response is a deformation of the superstructure, followed by a viscoelastic rearrangement of crystals within the deformed matrix. Dynamic mechanical behavior has been correlated with dynamic optical behavior in an effort to elucidate structural response mechanisms. (Author)
