An artificial snowseed in the form of granules of a super water-absorbing polymer already coated with a fluorine-containing material and/or a silicone oil. The granules can retain the original spherical form after absorption of water without sticking to each other. Further the present invention provides a method for making artificial snow comprising freezing the above artificial snowseed after absorption of water.

This invention provides a method for the manufacture of a high-expansion type absorbent polymer by first causing an absorbent polymer which is obtained by polymerization of a monomer and is possessed of an alkali salt of acrylic acid as a component of polymer to be cross-linked at the time of azeotropic dehydration thereof with a cross-linking agent possessing two or more functional groups in the presence of an inorganic salt and subsequently drying the cross-linked polymer. By the method of this invention, there can be obtained a high-expansion type absorbent material which absorbs water quickly and forms a gel not viscid but permeable to gas. This absorbent material is highly advantageously used as absorbent for sanitary materials free from leaking water and as a water-retaining agent for agricultural applications hardly causing rotton plant roots.
