Abstract

Se describen los absorbentes de polisacarida novedosos y un metodo para proporcionar una polisacarida modificada insoluble en agua e hinchable en agua teniendo propiedades de absorcion anejables preferidas. Los absorbentes de polisacarida novedosos y el metodo proporcionan un absorbente de base natural y caracteristicas de anejamiento preferidas para la absorbencia. Una carboxialquil polisacarida soluble en agua de base natural es disuelta en agua y se recupera y se tratan con calor para formar una carboxialquil polisacarida la cual es hinchable en agua e insoluble en agua. La carboxialquil polisacarida hinchable en agua e insoluble en agua teniendo un valor de absorbencia bajo carga inicial preferido se aneja bajo por lo menos alrededor de 60% de humedad relativa. En un aspecto la mezcla acuosa de la carboxialquil polisacarida soluble en agua tiene un pH de entre alrededor de 4.0 y alrededor de 7.5. El producto material de base natural teniendo una absorbencia bajo carga preferida y caracteristicas de anejamiento preferidas retiene por lo menos alrededor de 50% de un valor de prueba analitico de absorbencia bajo carga inicial despues del anejamiento.
