Synthesis and investigation of the efficiency of cationic aminopolymer resin

Experimental results of synthesis and investigation of the efficiency of a cationic aminopolymer resin are presented. The monomers are characterized, the synthesis conditions are considered, and the technical characteristics of the resin are given. It is shown that the resin facilitates the acceleration of dehydration of repulped stock, significantly reduces the cationic need, increasing the retention of anionic contaminations, and decreases the content of suspended substances in recycled water. The data on pilot tests of the resin are presented that demonstrate its high efficiency.
