| Abstract: | A high water absorbent polyacrylic acid was obtained by inverse suspension polymerization in the system of cyclohexane as continuons phase and water as dispersed phase. The effects on physical condition and water absorbability were studied under different amounts of base, crosslinking agent, initiator and at different temperature. This resin shows water absorbability 850 mL/g and in saline 120 mL/g (0.9% NaCl) respectively. |
