| titleOfInvention | Preparation of water absorbing resin |
| abstract | PURPOSE: To obtain a completely neutralized resin having improved water absorbing property, by adding an aqueous solution of a hydrogencarbonate of monovalent cation to an aqueous solution of polyacrylic acid having a specific neutralization degree or below (<100%) with the above-mentioned monovalent cation and aluminum ion. n CONSTITUTION: Sodium hydroxide is added to neutralize an aqueous solution of polyacrylic acid, e.g. 1% concentration, and an aqueous solution of aluminic acid is added thereto to give an aqueous solution of polyacrylic acid having <100% neutralization degree with the monovalent cation and aluminum ion. A hydrogencarbonate of the above-mentioned cation, preferably sodium hydrogencarbonate, in an amount of a little excess of 100% neutralization degree is added to the aqueous solution to give the aimed water absorbing resin automatically as a polyacrylate neutralized at 100% neutralization degree. n COPYRIGHT: (C)1984,JPO&Japio |
