ABSTRACT:
A new water-swellable composition of a gelling agent based on hydrolyzed homo- or copolymers of acrylonitrile and of an inert metal oxide was synthesized. In the process, 1 to 22% of the nitrile groups were saponified to amide groups and 99 to 78% to alkali-metal salts. The obtained composition had a spongy structure and was characterized by high values with regard to both swelling capacity and swelling rate. Therefore it is particularly suitable for diaper manufacture and for agricultural use.
