| Abstract: | The graft copolymerization of hydroxyethyl cellulose and N-isopropylacrylamide was initiated by CAN/HNO3.The reaction successful graft copolymerization was verified by IR spectrum and 1H-NMR spectrum.The effect of monomer content,initiator content and reaction temperature on the graft copolymerization was discussed.The solution properties of the graft copolymer were investigated by DSC and DLS.The results indicated that the graft copolymers were temperature sensitive. |
| Keywords: | hydroxyethyl cellulose N-isopropylacrylamide graft copolymerization temperature sensitive |
