Macrostructures of Porous Absorbent, Absorbent crosslinked particles adhered on the surface of aminoepiclorohidrina adducts with cationic and Method for making them

摘要

Method consists of the following steps: a) providing a multiplicity of particles of polymeric material.Forming hydrogel that have Anionic Functional groups; (b) treat these particles with an Adduct of aminoepiclorohidrina cationicIn an amount sufficient to react; (c) physically Associate to form an aggregate particles treated with interconnected pores by channels that intercommunicate,And (d) reacting the Adduct with the cationic polymeric material for the perticulas cross-linking Surface effectively and provide a macrostructure and porous Absorbent Aggregate and adheredEtween particles. Macrostructures are used in diapers, Adult incontinence pads, Sanitary Towels and similar
