The cellulose-poly (BMA) graft copolymer oil absorption resins has been synthesized from butyl methacrylate modified cotton pulp (cellulose) which initiated with ceric ion /HNO
3
solution by shake graft copolymerization using porcine pancreatic lipase as catalyze
N
N
′-methylene-bisacrylamide as crosslinker.Structure of the cellulose-poly (BMA) graft copolymer was characterized by means of FT-IR、XRD、SEM、TG、DSC etc.Effects of the process of initiating cotton pulp and graft copolymerization condition were investigated.The ideal cellulose-poly (BMA) graft copolymer oil absorption resins could be prepared when the cotton pulp initiated with 0.15mol/LHNO
3
solution of containats ceric ion at 45℃ for 2.5h
then reacted with BMA by using porcine pancreatic lipase as catalyze
N
N
′-methylene-bis-acrylamide as crosslinker.Under the optimal conditions of m (cellulose): m (initiator): m (monomer): m (porcine pancreatic lipase): m (crosslinker) =1∶0.03∶1.5∶0.02∶0.02
50℃ and 24h
the graft yield and oil pick-up abilities of the synthesized cellulose-poly (BMA) graft copolymer oil absorption resins are choiceness.
