Abstract
In this paper, we combine the recently proposed spherical harmonic expansion (SHE) method [Phys. Rev. X 2017, 7, 031003] with a modified network model to analyze the small-angle neutron scattering (SANS) spectra from deformed entangled polymers. Focusing on the leading anisotropic component and the isotropic component in the SHE, the analysis gives a reliable value of the stretch ratio of the end-to-end vector, and a reasonable estimation of the radius of gyration, of a single chain in polymers undergoing uniaxial deformation and relaxation. Moreover, it provides a practical way to evaluate the stress of deformed entangled polymers with the SANS spectra from a viewpoint of rubber elasticity.Citation
