The superabsorbent resin has become an indispensable material in all areas of the national economy by virtue of superior water absorption and water retention. However

the slow water absorption

poor salt tolerance

low gel strength and other issues of traditional super absorbent resin have restricted its development. In view of the increasingly obvious defects in the traditional superabsorbent resin

researchers have begun to study the synthesis and processing new methods of reducing resin production cost

improving biodegradability of resin

gel strength

water absorption and salt tolerance

so as to promote the use of products. Based on the recent research in this field

this paper summarizes the current performance defects of the superabsorbent resin

and puts forward the corresponding modification strategy to improve the comprehensive performance of the water absorbent resin.
