Title:
PRESSURE DISPERSION MATERIAL AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/023471
Kind Code:
A1
Abstract:
Provided is a pressure dispersion material that comprises a composite polymeric hydrogel to which suitable load dispersion properties, moisture permeability, and water-absorbing properties have been imparted. The pressure dispersion material comprises a porous gel which comprises: a three-dimensional network formed from (A) a polymer of a water-soluble organic monomer and (B) a clay mineral; and (C) a lowly volatile medium incorporated into the network. The lowly volatile medium (C) is a lowly volatile medium which has a volatility of 0.1 g/cm2·hr·60ºC·atm or less or a lowly volatile medium which has a vapor pressure measured at 20ºC of 1,000 Pa or lower and a boiling point measured at 1 atm of 130ºC or higher.
