SANS Mapping of Orientation and Relaxation of Polymer Chains upon Uniaxial Extension

POSTER

Abstract

Small angle neutron scattering (SANS) has been used to measure entangled chains in polymer melts upon uniaxial stretching. The degree of anisotropy and the coil dimension are discussed in the light of the applicability of the tube model.
