Abstract: Super absorbent resin prepared from modification of natural polymers as a kind of functional materials has developed rapidly in recent years. The unique chemical structure makes natural polymers can absorb water hundreds even thousands of times of their own weight. Natural polymers can also absorb some kinds of salt solutions in relatively large amount. The introduction of natural polymer into molecular structure made the obtained materials have good biodegradation ability，these materials can be widely used in agriculture and forestry production，urban gardening，water conservation and the fight to drought and desertification. This paper summarizes the progress of super absorbent resin prepared from modification of natural polymers，existing problems in application are discussed and further development prospects are proposed.
