-- BIODEGRADABLE SUPERABSORPTION POLYVINYLALCOHOL-GRAFT-POLYITACONIC ACID COPOLYMER AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to polyvinyl alcohol; Polytetaconic acid grafted to the polyvinyl alcohol and a cross-linking agent obtained by crosslinking the polyvinyl alcohol; Polyvinyl alcohol-graft-polybutanedicarboxylic acid copolymer. The present invention can provide a method for producing a biodegradable highly water-absorbing polymer having water solubility and biodegradability, less environmental burden due to disposal, and having high water absorption and absorption rate. In addition, since it is manufactured using a non-toxic raw material, when it is applied to sanitary products, it is harmless to the human body and can reduce skin irritation, and by using a low cost raw material, Can be developed.
