Process for manufacturing polymer-based absorbing material with improved degradability, absorption of water , aqueous solutions and body fluids and its use in sanitary articles and in soil amelioration

摘要

Production of an absorption material for water, aqueous solutions or bodily fluids from a water-swellable synthetic (co)polymer (A) and a natural or synthetic polymer (B) which is a flowable powder at normal temperatures and which is insoluble or only difficultly soluble in water comprises adding dry or partly swollen (B) to the production system for (A) at a conversion to (A) of ≥ 30 (especially ≥ 60)%, mixing with polymer (A) gel and then drying the product.
