  From a view point of reduction in an out of spec product after surface crosslinking, particularly, when an alkylene carbonate compound is used as a surface crosslinking agent, influence by an air temperature is great, and it is necessary to reduce ethylene glycol which is produced as a byproduct, and there is provided a process for producing a polyacrylic acid (salt)-based water absorbent resin powder, comprising a step of polymerizing an aqueous acrylic acid (salt)-based monomer solution, a step of drying the resulting polymer, an optional grinding·classifying step, and a surface crosslinking step, wherein in the surface crosslinking step, (1) a surface crosslinking agent containing an alkylene carbonate compound and a polyhydric alcohol compound is mixed into a water absorbent resin powder, the mixture is heat-reacted and, further, simultaneously with, or separately from the mixing, an ion reactive surface crosslinking agent is mixed, and/or (2) mixing treatment of mixing a surface crosslinking agent solution into a water absorbent resin powder containing at least one or more kinds of ion reactive surface crosslinking agents is performed two or more times.

  从减少表面交联后的不合规格产品的角度出发，特别是使用碳酸亚烷基化合物作为表面交联剂时，受空气温度的影响很大，有必要减少作为副产品产生的乙二醇，提供了一种生产聚丙烯酸（盐）基吸水性树脂粉末的工艺，包括 聚合丙烯酸（盐）基单体水溶液的步骤、 干燥所得聚合物的步骤、 可选的研磨分级步骤，以及 表面交联步骤、 其中在表面交联步骤中 (1) 将含有碳酸亚烷基酯化合物和多元醇化合物的表面交联剂混合到吸水性树脂粉末中，对混合物进行热反应，并在混合的同时或单独混合离子反应表面交联剂，和/或 (2) 将表面交联剂溶液与含有至少一种或多种离子活性表面交联剂的吸水性树脂粉末进行两次或多次混合处理。

  From a view pint of decreasing an out of spec product after surface crosslinking, particularly, when an alkylene carbonate compound is used as a surface crosslinking agent, influence due to an air temperature is great, and it is necessary to reduce ethylene glycol which is produced as a byproduct. There is provided a process for producing a polyacrylic acid (salt)-based water absorbent resin powder, comprising storing a non-polymerized organic compound being a raw material (modified raw material) of a water absorbent resin powder in a heated state, thereafter, mixing the non-polymerized organic compound with other compound at a predetermined ratio and, further, mixing the mixture into a water absorbent resin powder.

  从减少表面交联后的不合规格产品的角度来看，特别是在使用碳酸亚烷基化合物作为表面交联剂时，空气温度的影响很大，有必要减少作为副产品产生的乙二醇。 提供了一种生产基于聚丙烯酸（盐）的吸水性树脂粉末的工艺，包括将作为吸水性树脂粉末原料（改性原料）的非聚合有机化合物储存在加热状态，然后将非聚合有机化合物与其他化合物按预定比例混合，再将混合物混合成吸水性树脂粉末。
