Abstract
A radial distribution method for interpreting diffuse x‐ray diagrams of liquids has been utilized and further developed for an approach to the solution of structural problems of unoriented specimens of chain polymer substances. The principles of the technique have been given. Experimental distribution curves, indicating the atomic distance distributions have been calculated for the following chain polymers: polyvinyl acetate, polyvinyl alcohol, polystyrene, polyhexamethylene adipamide, polymethyl methacrylate, regenerated cellulose, and alginic acid. For the structure interpretation some of the experimental distribution curves are directly compared with theoretical distribution curves calculated from the atomic distances in measured out structure models, which have been built up on a scale of 1 A. equal to 10 cm. by means of a molecular model building set. From the results obtained, the technique seems to be well suited for structure investigations of unoriented samples of polymer substances.
