| Abstract: | PAA/PVA SIPN superabsorbents were synthesized by means of aqueous solution polymerization. The optimum synthesis conditions were: mAA∶mPVA=10∶0.5,the contents of initiator ( potassium persulfate ) and cross-linking agent ( N,N′-methylenebisacrylamide ) were 0.14% and 0.025%,respectively,degree of neutralization of AA was 80%. The polymer obtained under these conditions can absorb 530 g deionized water and 63 g NaCl solution ( wNaCl=0.9% ) per gram. The structures of polymers were analyzed by IR spectrometer. |
