吸水性树脂组合物及其制造方法
摘要：
本发明的目的在于对以吸水性树脂为主要成分的吸水性树脂组合物，在不损害吸水性树脂的外观和吸水特性的状况下赋予优异的除臭性和抗菌性。本发明的第一方式涉及的吸水性树脂组合物含有以聚丙烯酸(盐)系吸水性树脂为主要成分的吸水性树脂、竹提取物和茶提取物。本发明的第二方式涉及的吸水性树脂组合物含有以聚丙烯酸(盐)系吸水性树脂为主要成分的吸水性树脂和选自己酸(盐)、丁酸乙酯和3-甲基-2-环戊烯-1-酮所组成的组中的至少2种化合物。此外，本发明的第三方式涉及的吸水性树脂组合物的制造方法，在以丙烯酸(盐)为主要成分的不饱和单体聚合前或聚合后，添加竹提取物的醇溶液。
摘要（英）：

The invention aims to impart excellent deodorant and antimicrobial properties to a water-absorbing resin composition comprising a water-absorbing resin as the main component without impairing the surface appearance and water absorption characteristics of the resin. The first embodiment of the invention relates to a water-absorbing resin composition which comprises a water-absorbing resin component comprising a polyacrylic acid (salt) type water-absorbing resin as the main component, bamboo extract, and tea extract. The second embodiment of the invention relates to a water-absorbing resin composition which comprises a water-absorbing resin component comprising a polyacrylic acid (salt) type water-absorbing resin as the main component and at least two compounds selected from the group consisting of hexanoic acid (salt), ethyl butyrate, and 3-methyl-2-cyclopenten-1-one. The third embodiment of the invention relates to a process for the production of a water-absorbing resin composition byadding an alcoholic solution of bamboo extract before or after the polymerization of an unsaturated monomer component containing acrylic acid (salt) as the main component.
