A process for agglomerating a polymer powder which comprises mixing a polymer powder with an oxyalkylene group-containing polyvinyl alcohol resin in the presence of water and drying the resulting mixture. According to the process of the present invention, it is possible to easily prepare the polymer granules having little fine powder, a narrow particle size distribution and a large average particle size.

Process for agglomerating powder

A process for preparing particles of a high water-absorbent resin which comprises mixing a powder of a high water-absorbent resin having a water content of 10 to 60% by weight with a powder of water-soluble high molecular weight compound and drying the mixture. The obtained particles according to the present invention are suitable for use of sanitary goods, water-retaining agents or soil conditioner in the fields of agriculture and horticulture and other various uses.
