摘要

"Polissacaru00ecdeos absorbent and process for providing an inflatable polissacaru00ecdeo modified in water and insoluble in water which has absorption properties preferred stable after aging.Are described absorbent of polysaccharides and process to provide a modified polysaccharide inflatable in water and insoluble in water, which has absorption properties preferred stable after enVelhecimento. The absorbent unpublished polysaccharides and process offer a basic absorbent natural and preferred characteristics obtained after aging.A carbu00f3xi alkyl base natural water-soluble polysaccharide is dissolved in water.Recovered and subjected to heat treatment to become a carbu00f3xi alkyl polysaccharide that is inflatable in water and insoluble in water.The inflatable carbu00f3xi alkyl polysaccharide in water and insoluble in water with a value of absorbency under load initial preferred is aged at a relative humidity of at least approximately 60 porcThen. In one aspect, the aqueous mixture of carbu00f3xi - alkyl - water-soluble polysaccharide has a pH between about 4.0 and 7.5.The product of material of natural base with an absorbency under load and characteristics of aging favorite favorite retains at least approximately 50 percent of the value of analytical 'A state of absorbency under initial load after aging.
