It is described how to produce polyolefines and pol-yethers from thermoplasts by sulphation of polystirol. The polystirol is introduced into the propilen in the pro¬portion of 5 through 15% in mass. The largest static exchange capacity belongs to the fiber obtaind by treating it with a sulfic acid of 93% concentration under temperature of 100-105 grad.C. The acheived purification coeffitient for Cz-137 is near to that acheived on ion-exchanging material of КУ-2-10 type.
