"This thesis describes the development of a new process for the manufacture of spherical particles of cellulose, regenerated from cellulose zanthate.
An electric equipment manufacturing company advised the author’s company that it had developed a device that required uniform spheres of regenerated cellulose having a diameter of about 75 to 100 mils. This company reported that it had developed a process for the manufacture of the cellulose particles but that the spheres produced by the process were not uniformly spherical. The equipment manufacturer considered that the functioning of the new device could be improved if the cellulose particles could be made more nearly spherical.
The contact was made because the author’s company developed and owned the Ball powder process. It was thought that if nitrocellulose could be made into nearly perfect spheres by the techniques used in the manufacture of Ball powder, then cellulose zanthate could probably be formed into spheres by the same technique.
Attempts were made to regenerate cellulose zanthate in the shape of spheres using the well known Ball powder techniques, however, these procedures proved to be unsuited for the cellulose system and an entirely new procedure was developed, as described in the following pages"--Abstract, pages 1-2.
