Abstract: | Conclusions -- The process of preparing cation-exchange PCA fibers by the radical graft polymerization of potassium p-styrene-sulfonate in aqueous and in aqueous salt solutions of the monomer has been investigated. The identity of the kinetic parameters (reaction order with respect to monomer and the effective activation energy) of the heterophase graft polymerization of PSS indicates the occurrence of the graft polymerization in the kinetic region.-- A beneficial effect of the nature of the low-molecular electrolyte on the reaction rate and yield of graft polymer has been established; and the optimum content of electrolyte in the reaction mixture has been determined. Cation-exchange fibers have been obtained having an exchange capacity up to 1.3 meq/g.Translated from Khimicheskie Volokna, No. 2, pp. 12–14, March–April, 1993. |
