| Abstract: | The starch graft acrylamide copolymerization was studied with Tween as annexing agent,polyethylene glycol as dispersion medium and potassium permanganate as initiator.The effect of the type and concentration of Tween,PEG mass fraction,and the dosage of initiator concentration on monomer conversion,branch ratio,special number has been discussed.The structure of the copolymer was confirmed by FTIR.The optimum reaction conditions are 2% Tween-80,15% PEG 20000,n(potassium permanganate): n(acrylamide)=6.0×10-4 :1.Under this condition,the copolymer of monomer conversion is 99.71%,grafting ratio is 139.14%,intrinsic viscosity number is 477.63 mL/g. |
