QUADRIPOLYMER BASED ON HOST-GUEST INTERACTION AND PREPARATION METHOD THEREFOR

摘要

Disclosed are a quadripolymer based on a host-guest interaction and a preparation method therefor. The preparation process involves: (1) weighing maleic anhydride, dissolving same in dichloromethane, dropwise adding β-phenylethylamine, stirring and reacting same for 1-3 hours, and suction filtering, washing and vacuum drying same to obtain N-phenylethylmaleamic acid; (2) weighing mono-6-ethylenediamine β-cyclodextrin and maleic anhydride, dissolving same in N,N-dimethylformamide, reacting same for 3-6 h at 40℃, allowing a product to precipitate out by using chloroform, and washing and vacuum drying same to obtain maleic anhydride-modified mono-6-ethylenediamine β-cyclodextrin; and (3) adding acrylamide, acrylic acid, the maleic anhydride-modified mono-6-ethylenediamine β-cyclodextrin and N-phenylethylmaleamic acid to distilled water, adjusting the pH value of the solution to 7, introducing nitrogen to remove oxygen, adding a photoinitiator, and placing same in a light-initiation device for a reaction of 3-5 hours at a reaction temperature of 10-30℃. The quadripolymer has a better temperature and salt resistance and shear resistance, the raw materials thereof are cheap and easily available, and the reaction conditions are mild. Same has broad market application prospects.
