Abstract The x‐ray scattering method has been used to investigate the structure in two amorphous crosslinked polymers which are regarded as test systems to establish the power of the method as applied to amorphous biologically significant polymer associations. It is shown that structural information can be determined about the rigid regions within the polymer systems, i.e., those regions held in particular configuration by stereochemical effects. Models of such regions extending over distances with dimensions of ca 18 Å are proposed for an Araldite polymer and for crosslinked poly (methyl/butyl methacrylate). The results allow some general statements about the usefulness and limitations of the amorphous x‐ray method.
