Title:
METHOD FOR PRODUCING CARBOXYALKYLCELLULOSE POLYMER NETWORK
Document Type and Number:
Japanese Patent JP2006188697
Kind Code:
A
Abstract:
To provide a method for producing a carboxyalkylcellulose polymer network having high water-absorbing property.
The polymer network is produced by reacting a carboxyalkylcellulose produced from a pulp having a kappa value of about 1 to about 65 with a crosslinking agent of an amount effective for making the carboxyalkylcellulose to be insoluble in water. The crosslinking agent is aldehydes, dialdehydes, dialdehyde sodium bisulfite addition products, dihalogenated compounds, dienes, diepoxides, etc.
