摘要： PURPOSE:To obtain the subject molding which can shrink within a short time even at a low temperature merely by absorbing moisture and is capable of package, etc., suited for the shape of an irregularly shaped article by stretching a graft copolymer of a hydrophilic resin with a thermoplastic resin. CONSTITUTION:A moisture-shrinking resin molding is obtained by stretching a graft copolymer of a hydrophilic synthetic resin (a nonionic resin, an anionic resin, a cationic resin or an amphoteric resin) with a thermosetting resin (particularly desirably one containing an acrylic ester elastomer), e.g. PVA/methyl acrylate graft copolymer. This molding can be conveniently used without requiring any special shrinking apparatus and can shrink within a short time when it absorbs moisture even at a low temperature. When an irregularly shaped article is wrapped wit the molding in the form a film and left under high humidity conditions, the film can shrink in conformity with the shape of the article and can pack it. Therefore, the molding can be used for a heat-sensitive article to which any conventional shrinking resin composition cannot be applied.

摘要： PROBLEM TO BE SOLVED: To obtain a water absorbing resin as particles, which has a great water retention amount, a little content of a water-soluble component, and a relationship between the water retention amount and water absorption amount under a load, and particularly, has a balance at a high level of the water absorption amount under the heavy load. SOLUTION: In a preparation method of the water absorbing resin comprising radical-polymerizing at least one radical polymerizable monomer which is a water-soluble and/or becomes water-soluble by a hydrolysis and a crosslinking agent in the presence of water, the method is characterised by polymerizing the reactants together with at least one compound (C) selected among a benzotriazole series compound, a benzophenone series compound, a triazine series compound, a hindered amine series compound, and a hindered phenol series compound. Further, according to a surface crosslinking of the resulting water absorption resin as the partilces, the absorption performance under the load is improved while holding high water retention amount.
