Hydroabsorbent resins, production method and application thereof for obtaining articles capable of absorbing aqueous fluids

摘要

Water-absorbing resin based on acrylic acid and on dialkylaminoalkyl acrylate. It comprises from 40 to 60% on a molar basis of acrylic acid, at least partially in salt form if appropriate, and from 60 to 40% on a molar basis of at least one dialkylaminoalkyl acrylate, at least partially in salt form or quaternized if appropriate. It is manufactured by copolymerization either in aqueous solution or in an inverse emulsion, in the presence of at least one free-radical generator. Application to the production of articles capable of absorbing aqueous liquids.
