Biologisch abbaubares Absorptionsmittel

摘要

A solid absorbing agent for water, aqueous solutions and body fluids is produced by cross-linking an ionic, carboxyl-containing polysaccharide derivative in the presence of 10-80 % by weight water (with respect to the polysaccharide derivative) at 110-180 DEG C. The solid absorbing material is characterised in that is consists of 100 % biodegradable renewable raw materials and in that it exhibits the qualities required of such materials in hygienic or medical articles, for example.
