This chapter describes polymers. The importance of small-angle neutron scattering for studying polymers has arisen first from the labelling possibilities offered by the large differences in the scattering lengths of hydrogen and deuterium, and second from the available Q-range, which allows exploration of distance scales from a few repeat segments up to the dimensions of whole molecules. Their high molecular weight excludes a gaseous phase for polymer molecules, and the liquid phase is markedly different from low-molecular-weight species, the molecular entanglements giving rise to the viscoelastic properties typical of rubbery materials. Dilute solution is the nearest approach to the gaseous phase for polymers and while this state was thoroughly explored by the older light and x-ray scattering techniques, exploration of changes in conformation introduced as concentration increases up to the bulk state has proved a fruitful field for neutron scattering studies. The intramolecular motion of macromolecules is classified under three headings: vibrations and rotations of side chains, vibration of the main chain in crystalline samples, and main-chain motion in solutions and melts. © 1987, Academic Press, Inc.

Higgins JS, 1985, LIGHT, NEUTRON AND X-RAY SCATTERING TECHNIQUES FOR STUDYING POLYMER BLENDS., Pages: 69-88, ISSN: 0168-132X

This paper outlines the principles of scattering theory and explains the applications to study of blends. All scattering experiments are based on the existence of variations in the homogeneity of the scattering medium. These may arise either because a few molecules of one type are embedded in a matrix of others, as in dilute solutions, or because of concentration fluctuations in a high concentration mixture or from density fluctuations in a single component system. If these inhomogeneities also cause variation in the physical property relevant for scattering a particular type of radiation, a scattering pattern may result. These relevant properties are the polarisability (or refractive index) for light, the electron density for X-rays and the scattering length density (a nuclear property) for neutrons.
