Abstract

Two synthetic methods of polyvinyl alcohol with high absorbency for saltliquor were described: (1) Make partially phosphorylated polyvinyl alcohol crosslinking using Zr(IV) salt as crosslinking agents. (2) Make polyvinyl alcohol

free phosphoricacid and ZI(IV) salt forming crosslinking complex resin. The absorbency of synthesizedcomplex resin for 1% NaCl liquors is above 100 times by both (1) and (2). It is fairly stable in water

salt solutions

great major dilute solutions of acid

and non-aqueous solvents.A structure of this complex resin was proposed on the basis of chemical analysis

IR spectra and the theory of zirconium chemistry and making it compare with those of model reaction.
