    • An object of the present invention is to provide a water-soluble acrylate polymer that can form a gelling base. When used in forming a poultice or cooling sheet, the gelling base not only imparts desirable stretchability, but also has an appropriate reaction rate with a polyvalent metal. The gelling base is free from gel penetration to the back side of a support or gel seeping from the support while the gel is being cured, and is easily applied to the support. When the gelling base is gelated by being allowed to stand under the conditions of 25° C. and a relative humidity of 60%, the gel strength is 3,200 to 7,000 dyn/cm2 after standing for 7.5 hours and 5,000 to 9,000 dyn/cm2 after standing for 200 hours, and satisfies the following relationship: Gel strength after standing for 7.5 hours]≦Gel strength after standing for 200 hours.
    • 本发明的目的是提供可以形成胶凝基质的水溶性丙烯酸酯聚合物。 当用于形成泥敷剂或冷却片时,胶凝剂不仅赋予所需的拉伸性,而且与多价金属具有适当的反应速率。 当凝胶固化时,胶凝基体不会凝胶渗透到支撑体或凝胶从支持体渗出的背面,并且容易地施加到载体上。 凝胶化凝胶化后,在25℃,相对湿度60%的条件下凝胶化,静置7.5小时后的凝胶强度为3200〜7000dyn / cm2,后处理为5000〜9000dyn / cm 2 静置200小时,静置7.5小时后的凝胶强度为>静置200小时后的凝胶强度。
