Abstract

POSTUPAK ZA DOBIJANJE HIDROSAMSKIH POLIMERA AKRILAMIDA, reagovanjem vodenog rastvora akrilamidnog polimera sa hidroksilaminskom soli pri molskom odnosu hidroksilamina prema amidnim grupama u akrilamidnom polimeru od oko 0,1 do oko 0,2, poboljšanje je naznačeno time, što se reakcija izvodi prema pH najmanje približno 8,0 i temperaturi koja je u opsegu od oko 20- 100 C. Prijava sadrži još 7 zahteva.
