Small‐angle neutron scattering is a molecular probe to monitor chain conformations in partially deuterated polymers. It can also be used to investigate the morphology of microphase segregated multiphase systems. It offers a means of understanding polymer microstructure, which can then be related to physical properties and sample treatments. This technique is applied here to the problem of macromolecular orientation in polystyrene subject to hot‐stretching as well as to a block copolymer system (50/50 mixture of bisphenol A carbonate and dimethylsiloxane). A general description of the technique as well as specific results are discussed.
