This investigation was started at the suggestion of Dr. P. C. Scherer who suggested that a film prepared from a cellulose xanthate, in which the fiber form had been destroyed by some action other than by dilute alkali, should have interesting properties. The possibilities of such a material might be much greater if the destruction of the fiber form were brought about by a kneading action. This investigation was purely a qualitative one and no attempt has been made to test any of the products other than by appearance and general properties. The main object was that of finding ways and means of handling the material in an attempt to prepare a product of some strength and plasticity. The results obtained in all of the preceding experiments emphasize the difficulty which is encountered in the attempt to plasticize a cellulose xanthate and the removing of the salts formed in the xanthate formation. The removal of the salts in the water treatment (B) required large amounts of water which also seemed to remove the plasticizer. Some of the plasticizers were soluble in alkaline solutions and in the dissolving out of the salts, the dissolved salts caused high causticity, thus removing the plasticizer also. The acid-treated samples (A) and (C) required from three to four hours to completely dissolve the salts present in the sample. This treatment probably caused a high degree of degradation since all of the samples were brittle and had less strength than the water-treated samples. Since the results of the investigation are all negative in so far as the main object was concerned, it is concluded that a plasticized cellulose cannot be obtained from. cellulose xanthate using the plasticizers and methods set forth in this investigation. / M.S.
