Zwitter-ionic polymer vinyl sulfone derivative and preparation and application methods thereof

The invention discloses a zwitter-ionic polymer vinyl sulfone derivative and preparation and application methods thereof. The zwitter-ionic polymer vinyl sulfone derivative has a structure shown as the formula I. The prepared zwitter-ionic polymer vinyl sulfone derivative can maintain scale resistance and biocompatibility of zwitter-ionic polymers, vinyl sulfone function groups at one end are highin reactivity and meanwhile have the advantages of being hydrolysis resistance, alkali resistance and broad reaction spectrum. By taking the advantage of reaction proneness of vinyl sulfone to hydrosulfuryl and amino, the zwitter-ionic polymer vinyl sulfone derivative can introduce polymer chains onto the surface of materials, so that the zwitter-ionic polymers can achieve certain application values. 本发明公开了种两性离子聚合物的乙烯基砜衍生物、其制备方法及应用，该两性离子聚合物的乙烯基砜衍生物具有通式I的结构。该方法所制备的产品在保持了两性离子聚合物的抗垢性和生物相容性，而端的乙烯基砜官能团，有很高的反应活性，同时具有耐水解性、耐碱性和反应广谱性等优点，可以利用乙烯基砜易于和巯基、氨基反应的特性，可以把聚合物链引入到材料表面，所以两性离子聚合物具有定的应用价值。
