    • A multi-vinylsulfone containing molecule is described herein. The multi-vinylsulfone containing molecule can be formed by dissolving a water soluble polymer containing a hydroxyl group in an aqueous solution to form a polymer solution; adding a molecule containing two vinylsulfone groups to the polymer solution; and forming a modified polymer by controlling a number of the vinylsulfone groups that are added to the polymer. A hydrogel is also described herein that can include the multi-vinylsulfone containing molecule and a multi-thiol containing molecule. The hydrogel can be formed from an aqueous solution that includes the multi-vinylsulfone containing molecule and the multi-thiol containing molecule by undergoing gelatation upon delivery to a site in the body. Also described is a drug delivery system that employs the hydrogel.
    • 本文描述了含有多乙烯基砜的分子。 含有多乙烯基砜的分子可以通过将含有羟基的水溶性聚合物溶解在水溶液中形成聚合物溶液而形成; 向聚合物溶液中加入含有乙烯基砜基团的分子; 以及通过控制添加到聚合物中的数量的乙烯基砜基来形成改性聚合物。 本文还描述了可以包括含有多乙烯基砜的分子和含多硫醇的分子的水凝胶。 水凝胶可以由含有多乙烯基砜的分子和含多硫醇的分子的水溶液形成,通过在递送到体内的部位时经历凝胶化。 还描述了采用水凝胶的药物递送系统。
