Preparation and properties of fibers containing mixed polymers. II. Polyacrylonitrile‐cellulose fibers

Abstract

AbstractIn the previous paper the preparation and properties of fibers containing both polyacrylonitrile and cellulose acetate were discussed. It has proved possible to hydrolyze the cellulose acetate without extensive side reactions to produce fibers containing both cellulose and polyacrylonitrile. The properties of such fibers are discussed in this paper. The fibers have been examined optically and using x‐ray diffraction techniques. The absorptive capacity for water and direct dyes, the density, the electrical resistivity, and the mechanical properties of the fibers have been measured. The results are compatible with a structure consisting of submicroscopic regions of each polymer throughout the fiber interspersed with void spaces that are probably produced during drawing.
