Abstract
(EN)
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.

L'invention concerne un quadripolymère basé sur une interaction hôte-invité et son procédé de préparation. Le procédé de préparation consiste à : (1) peser l'anhydride maléique, dissoudre celui-ci dans du dichlorométhane, ajouter goutte à goutte de la β-phényléthylamine, agiter et faire réagir celui-ci pendant 1 à 3 heures, et filtrer par aspiration, laver et sécher sous vide celui-ci pour obtenir de l'acide N-phényléthylmaléamique ; (2) peser la mono-6-éthylènediamine β-cyclodextrine et l'anhydride maléique, dissoudre celle-ci dans du N,N-diméthylformamide, faire réagir celle-ci pendant 3 à 6 h à 40 °C, permettant à un produit de précipiter en utilisant du chloroforme, et laver et le sécher sous vide celui-ci pour obtenir une mono-6-éthylènediamine beta-cyclodextrine modifiée par un anhydride maléique ; et (3) ajouter de l'acrylamide, de l'acide acrylique, de la mono-6-éthylènediamine β-cyclodextrine modifiée par l'anhydride maléique et de l'acide N-phényléthylmaléamique à de l'eau distillée, ajuster la valeur de pH de la solution à 7, introduire de l'azote pour éliminer l'oxygène, ajouter un photo-initiateur, et placer de celui-ci dans un dispositif de déclenchement de lumière pour une réaction de 3 à 5 heures à une température de réaction de 10 à 30 °C. Le quadripolymère a une meilleure résistance à la température et au sel et une résistance au cisaillement, les matières premières de celui-ci sont bon marché et facilement disponibles, et les conditions de réaction sont douces. Ledit quadripolymère a de bonnes perspectives d'application industrielles.
