| titleOfInvention | Quadripolymer based on host-guest interaction and preparation process thereof |
| abstract | A quadripolymer based on host-guest interaction and prepared in the steps including (1) weigh maleic anhydride and dissolve in dichloromethane, add β-phenethylamine dropwise, stir to react for 1 to 3 hours, perform extraction filtration and washing, to obtain N-phenethylmaleamic acid; (2) weigh mono 6-ethylenediamine β-cyclodextrin and maleic anhydride, dissolve in N, N-dimethylformamide, and place at 40° C. for reaction for 3 to 6 hours, the product is precipitated with chloroform, washed and dried under vacuum to obtain maleic anhydride modified mono 6-ethylenediamine β-cyclodextrin; (3) Add acrylamide, acrylic acid, maleic anhydride modified mono 6-ethylenediamine β-cyclodextrin, N-phenethylmaleamic acid, adjust the pH of the solution to 7; introduce nitrogen, add a photoinitiator and place to a photo-initiating device to react 3˜5 hours at a temperature of 10˜30° C. The quadripolymer has good temperature and salt resistance, shear resistance. The raw materials are cheap and easily available. The reaction conditions are mild. |
