The use of lactam-containing complex salts (LCS) with the functions of dispersants, apparatuses and crosslinking agents made it possible to obtain elastomers with a high (at least 300 wt.% per 100 wt.h. of rubber), containing modified carboxymethyl cellulose for the cuff of a packer device capable of performing the necessary shut-off functions in contact with highly concentrated, at least 25% aqueous solutions of mineral salts - NaCl and CaCl2. The achieved effect is expressed in the ability of LCS to disperse water-swelling polymers (GNP), to have an appreting effect on GNP particles, thereby preventing their agglomeration, as well as to create additional chemisorption bonds in the rubber matrix. As a result, a developed network of interface boundaries is obtained, which contributes to the rapid penetration of aqueous solutions of mineral salts into the array of elastomeric composition.
