Abstract

"ABSORVENTES DE POLISSACARìDEOS E PROCESSO PARA PROVER UM POLISSACARìDEO MODIFICADO INFLáVEL EM áGUA E INSOLúVEL EM áGUA QUE TEM PROPRIEDADES DE ABSORçãO PREFERIDAS ESTáVEIS DEPOIS DE ENVELHECIMENTO". São descritos absorventes de polissacarídeos e processo para prover um polissacarídeo modificado inflável em água e insolúvel em água que tem propriedades de absorção preferidas estáveis depois de envelhecimento. Os absorventes inéditos de polissacarídeos e processo propõem um absorvente de base natural e características preferidas de absorvência depois de envelhecimento. Um carbóxi-alquil polissacarídeo de base natural hidrossolúvel é dissolvido em água, recuperado e submetido a tratamento térmico tornando-se um carbóxi-alquil polissacarídeo que é inflável em água e insolúvel em água. O carbóxi-alquil polissacarídeo inflável em água e insolúvel em água com um valor de Absorvência sob Carga inicial preferido é envelhecido a uma umidade relativa de pelo menos aproximadamente 60 porcento. Em um aspecto, a mistura aquosa de carbóxi-alquil-polissacarídeo hidrossolúvel tem um pH entre aproximadamente 4,0 e 7,5. O produto de material de base natural com uma absorvência sob carga preferida e características de envelhecimento preferidas conserva pelo menos aproximadamente 50 porcento do valor analiticamente testado de Absorvência sob Carga inicial depois do envelhecimento."POLysaccharide Absorbents and Process for Providing a Water-Insoluble and Water-Insoluble Modified Polysaccharide that has Preferred Absorption Properties after Aging". Polysaccharide absorbers and process for providing a water-insoluble and water-insoluble modified polysaccharide having preferred stable absorption properties after aging are described. Unprecedented polysaccharide and process absorbers offer a natural-based absorbent and preferred absorbency characteristics after aging. A water-soluble naturally occurring carboxyalkyl polysaccharide is dissolved in water, recovered and heat treated to become a water-insoluble water-insoluble carboxyalkyl polysaccharide. Water-insoluble and water-insoluble carboxyalkyl polysaccharide with a preferred initial Absorbance value is aged at a relative humidity of at least about 60 percent. In one aspect, the aqueous water-soluble carboxyalkyl polysaccharide mixture has a pH between about 4.0 and 7.5. The natural base material product with a preferred absorbance under load and preferred aging characteristics retains at least about 50 percent of the analytically tested value of initial absorbance under aging after aging.
