The influence of imbibed water in cellulose, polypropylene, and polyester on their x‐ray diffraction patterns has been studied. It was found that both hygroscopic and nonhygroscopic polymers behave similarly, in that the resolution of the peaks in their x‐ray diffraction patterns increases. This is because the addition of water enhances the x‐ray absorption coefficient of the polymers which are poor absorbers of x‐rays in their dry state. It is concluded that there is no x‐ray evidence at present which indicates that water has an influence on the cellulose lattice.
