| Abstract: | Conclusions In the action of  -radiation on solutions of cellulose xanthate, the molecular weight nonuniformity of the polymer in solution is reduced, which is one of the reasons for the anomalous decrease in dynamic viscosity of the solution.The irradiated solutions of cellulose xanthate are characterized by increased homogeneity and stability with time as compared with unirradiated solutions.The considerable decrease in viscosity of cellulose xanthate solutions and the increase in its homogeneity under the action of high energy ionizing radiation present practical interest, since these make it possible to obtain solutions of cellulose xanthate with a comparatively low viscosity at high values of mean degree of polymerization and of polymer content of the solution.Transition of part of the -fractions (DP 50) into  -cellulose (DP150 and 200) has been detected, which may be a consequence of radiochemical polymerization (cross-linking) in a solution of -cellulose or -cellulose and -cellulose.Translated from Khimicheskie Volokna, No. 5, pp. 24–26, September–October, 1989. |
