Description
Summary:The application of spin‐polarized neutrons with spin polarization analysis to study diffraction patterns from polymers is discussed. The experimental separation of the coherent and incoherent parts of the scattering coupled with the use of the internal standard resulted in the quantitative analysis of the purely coherent scattering from unfunctionalized and functionalized polystyrene in terms of absolute units. This allowed us to model the scattering curves in terms of paracrystallinity. © 1993 John Wiley & Sons, Inc.
