Oxidation and aging of cellulose
Macromolecular Symposia, 1997AbstractOxidation of cellulose by chlorine, bromine, hydrogen peroxide and ozone and the functional groups formed are reviewed. The roles of the pH and of the nature of the oxidant in the formation of carboxy‐ and keto‐celluloses are discussed. The relationships between the functional groups, degradation and stability of the celluloses enable to ...

In vivo degradation of oxidized, regenerated cellulose
Carbohydrate Research, 1990Oxidized, regenerated cellulose (ORC) was surgically implanted on the uterine horns of rabbits, and its biodegradation was studied in vivo. Samples of peritoneal lavages, serum, and urine were collected during the degradation process and analyzed for carbohydrate components utilizing high-performance liquid chromatography with pulsed amperometric ...

TEMPO-Mediated Oxidation of Cellulose III
Biomacromolecules, 2003Various cellulose samples converted into cellulose III by two different ammonia treatments, either liquid or gaseous, were reacted with catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO), sodium hypochlorite, and sodium bromide in water.

Oxidized Regenerated Cellulose for Hepatic Hemostasis
Archives of Surgery, 1963Introduction Oxidized regenerated cellulose is a relatively recent addition to the surgeon's armamentarium for hemostasis. Its hemostatic and absorbable qualities have been attested to by several authors in recent articles. 1-5 There have also been several articles describing its chemical nature, the mechanism of solubility in human tissues, and ...

Biodegradation studies on periodate oxidized cellulose
Biomaterials, 1982Abstract Sodium periodate oxidized cellulose was found to degrade into small molecules when implanted subcutaneously in rats. Thus the potentiality of using oxidized cellulose as a biodegradable drug carrier is envisaged.
