Superabsorbent polymer particles comprising functionalizers and method of making them
摘要：
The present invention relates to superabsorbent polymer particles having functionalizers covalently bound to the surface of precursor superabsorbent polymer particles. The functionalizers of the present invention comprise a grafting unit with a radiation activatable group and a functional unit covalently bound to the grafting unit. The grafting unit is bound to an aliphatic C—H group comprised at the surface of the precursor superabsorbent polymer particle. The functional unit comprises chemical structures which are not present in the precursor superabsorbent polymer particle. These functional units add an additional function to the precursor suberabsorbent polymer particle or modifying an existing function of the precursor superabsorbent polymer particle. Moreover, the invention relates to a process for making these superabsorbent polymer particles.
摘要（中）：

本发明涉及具有与前体超吸收性聚合物颗粒的表面共价结合的官能化物的超吸收性聚合物颗粒。 本发明的功能化剂包括具有可辐射活化基团和与接枝单元共价结合的官能单元的接枝单元。 接枝单元与包含在前体超吸收聚合物颗粒表面的脂族C-H基团结合。 功能单元包括不存在于前体超吸收聚合物颗粒中的化学结构。 这些功能单元向前体抗氧化剂聚合物颗粒添加附加功能或改变前体超吸收聚合物颗粒的现有功能。 此外，本发明涉及制备这些超吸收性聚合物颗粒的方法。
