A highly water-absorbent gel of vinyl alcohol/sodium acrylate copolymer was ground in a vacuum and in an inert dry gas to obtain fine particles. We obtained products with a mean size of 3.5 μm after grinding for 24 h. Products ground in a vacuum and in nitrogen were slightly smaller than those ground in argon and in helium. We investigated the effect of attapulgite added to the feed on the size of the ground products and found that it was effective for up to 10 h for producing fine particles. The relation between particle size and water absorbency of ground products with and without the attapulgite was also investigated. For particle sizes greater than 5 μm, the water absorbency of ground products was slightly higher than or the same as that of the feed. The water absorbency decreased with particle size for particles smaller than 5 μm, especially in the case of grinding with attapulgite.
