摘要：
The present invention relates to superabsorbent polymer particles with improved surface cross-linking and improved hydrophilicity and their use in absorbent articles. Superabsorbent polymer particles of the invention consist of cross-linked poly(meth)acrylic acid and salts thereof. The polymer chains comprised by the superab-sorbent polymer particles are cross-linked to each other through direct covalent bonds and comprise alcoholic hydroxyl groups. Moreover, the invention relates to a method for surface cross-linking superabsorbent polymer particles using vacuum UV irradiation.
摘要（中）：
本发明涉及具有改进的表面交联和改进的亲水性的超吸收性聚合物颗粒及其在吸收制品中的用途。 本发明的超吸收性聚合物颗粒由交联的聚（甲基）丙烯酸及其盐组成。 由超级吸收剂聚合物颗粒组成的聚合物链通过直接共价键彼此交联并且包含醇羟基。 此外，本发明涉及使用真空UV照射来表面交联超吸收性聚合物颗粒的方法。
