Utilization of CMC and PVA for the Preparation of Superabsorbent Resin

Abstract:

A blend superabsorbent resin from CMC and PVA grafted acrylic acid was prepared by solution polymerization without crosslinker. It was characterized by TG to understand thermal stability. SEM and ESEM was used to observe the surface morphology and the network structure. And the absorbency in double distilled water and in 0.9% NaCl solution was measured. The results showed the superabsorbent resin synthesized in this study is stable at temperature lower than 385°C. The thermal stability is good. SEM results indicated that dry resin has rough surface on cross section and good property of membrane. It is found in ESEM photographs that it has uniform network structure made from numerous connecting polygonal membranes and there are holes on the membranes. The absorbency in distilled water and 0.9% NaCl solution are1392.9g/g and 128.5g/g. It has high swelling rate and good salt-resistance.
