The present invention discloses a process for manufacturing a grafted polyacrylamide flocculant of cationic/ampholytic ions, which is characterized by graft-copolymerizing starch or micro-crystalline cellulose as backbone with acrylamide, while
In order to prepare a cellulose-based water absorbent material in an environmentally-friendly way, a cellulose-graft-polyacrylamide (cellulose-g-PAM) copolymer is synthesized by in situ graft copolymerization through a co-rotating twin-screw
