The present invention discloses a quadripolymer based on host-guest interaction and preparation process thereof. The preparation process: (1) weigh maleic anhydride and dissolve in dichloromethane, addβ-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 and shear resistance, and its raw materials are cheap and easily available, the reaction conditions are mild, having broad market application prospects.
