Neutron Scattering from Polymers

JAN 01, 1985
The great difference in scattering power between a deuterated polymer and its hydrogenous counterpart allows one to determine the shapes and movements of polymers in solutions, melts, gels and crystals.
Richard S. Stein

Some years ago, one of our mentors expressed the desire to “color polymer molecules red” so that one could follow them in a solid and see how they arrange themselves and how they move among similar or different molecules. As we will see in this article, the excitement today over the application of small‐angle neutron scattering to the study of polymers lies in the possibility of fulfilling his wish to understand the conformation and dynamics of polymer molecules.
