Process for preparing thermoplastic regenerated cellulose

Claim 1

A PROCESS FOR PREPARING THERMOPLASTIC REGENERATED CELLULOSE WHICH DISPLAYS AN AMORPHOUS STRUCTURE UNDER XRAY DIFFRACTION AND IS CHARACTERIZED BY DEFORMABILITY UNDER HEAT AND PRESSURE WHICH COMPRISES MIXING A CELLULOSE FORMATE ESTER WITH WATER AND A PLASTICIZER FOR CELLULOSE AT A TEMPERATRUE OF 20*C. TO 65*C. TO PRODUCE A MIXTURE OF AMORPHOUS REGENERATED CELLULOSE AND FORMIC ACID, SAID WATER BEING EMPLOYED IN AN AMOUNT OF AT LEAST FIVE MOLES PER ANHYDROGLUCOSE UNIT IN SAID FORMATE ESTE, SID PLASTICIZER BEING CHOSEN FROM THES GROUP CONSISTING OF A POLYHYDRIC ALCOHOL CONTAINING 2 TO 6 CARBON ATOMS AND A POLYVINYL ESTER OF ACETIC ACID, PROPIONIC ACID, BUTYRIC ACID, STEARIC ACID, LAURIC ACID, AND MYRISTIC ACID, REMOVING THE FORMIC ACID FROM SAID MIXTURE, REDUCING THE MOISTURE CONTENT OF SAID AMORPHOUS REGENEATED CELLULOSE AT A TEMPERATURE RANGE OF ABOUT 25*C. TO 65*C. TO A VALUE OF ABOUT 7 TO 15 PARTS OF WATER PER 100 PARTS BY WEIGHT OF SAID AMORPHOUS REGENERATED CELLULOSE, WITH SAID AMORPHOUS REGENERATED CELLULOSE CONTAINING PLASTICIZER TO THE EXTENT OF ABOUT 50 TO 150 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF REGENERATED CELLULOSE.
