Depolymerization of cellulose fibers during irradiation is accompanied by a reduction in crystallinity, and, at high doses, extensive decomposition occurs. A dose of 5 X 10 equivalent roentgens brings about marked degradation and is sufficient to convert cotton linters into water-soluble materials. After irradiation, cellulose is more susceptible to acid hydrolysis and exhibits an after-effect. When irradiation is terminated, the intrinsic viscosity of cupriethylenediamine solutions of the irradiated cellulose continues to decrease. This behavior is initiated by oxygen and terminated by water. A similar effect is encountered with pectins after irradiation. [Pg.34]

Viscosities of samples of cellulose were measured as 0.5% solutions in cupriethylenediamine by the viscosity pipet method 28). [Pg.126]

The IV of cellulose is determined by measuring the viscosity of a very dilute solution (such as 0.5%) of the cellulose in cupriethylenediamine hydroxide (abbreviated cuene) or cuprammo-nium hydroxide (abbreviated cuam). A relationship has been developed between IV and DP so that the two can be used interchangeably. [Pg.777]

The molecular cellulose chains have varying lengths. Measurements of the chain length require that cotton be in solution. Solvents for this purpose include cuprammonium hydroxide solution, phosphoric acid [7664-38-2], nitric acid [7697-37-2], quaternary ammonium bases, cadmium ethylenediamine hydroxide [14874-24-9], cupriethylenediamine hydroxide [111274-71-6] (76), dimethylacetamide [127-19-5]-lithium chloride [7447-41-8] (DMAC—LiCl), and... [Pg.1947]
