    摘要: A process for producing water-soluble, cationic polyelectrolytes is described, wherein the polymerization of the water-soluble monomers is initiated at low temperatures using a combination of UV light, photoinitiator and a redox system, and is characterized in that the redox system is capable of initiating the polymerization only at temperatures higher than or equal to 20° C. The polymers have a high molecular weight and a low content of residual monomer.

    摘要: A process for producing an absorbent polymer structure (Pa) by treating the outer portion of an untreated absorbent polymer structure (Pu1). The process includes the step of bringing the outer portion of the untreated absorbent polymer structure (Pu1) into contact with an aqueous solution including at least one chemical cross-linker and at least one inorganic compound in dispersed colloidal form. The process also includes the step of heating the absorbent polymer structure, of which the outer portion has been brought into contact with the aqueous solution, at a temperature within a range from about 40 to about 300° C., so that the outer portion of the absorbent polymer structure is more strongly cross-linked in comparison to the inner portion and the inorganic compound is at least partly immobilized in the outer portion of the absorbent polymer structure.
