Title:
METHOD OF PRODUCING WATER-ABSORBING RESIN COMPOSITION AND WATER-ABSORBING RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/141875
Kind Code:
A1
Abstract:
It is intended to provide a water-absorbing resin composition in which the liquid diffusion properties (i.e., meaningful characteristics in practice) have been largely improved without worsening the fundamental water-absorbing performance, productivity and so on as a water-absorbing resin material to be used as a water-absorbing material in paper diapers, etc. A method of producing a water-absorbing resin composition which involves the step of mixing a water-absorbing resin A with inorganic microparticles B having been irradiated with ultraviolet light so that the amount of the inorganic microparticles B is controlled to from 0.01 to 10 parts by weight per 100 parts by weight of the water-absorbing resin A. Thus, a water-absorbing resin composition having a liquid diffusion velocity (LDV) of from 2.0 to 10 mm/s can be produced.
