| Abstract: | Polyaspartic acid superabsorbent resin with hydroxyl(HPASP) was prepared by using poly-succinimide(PSI) as raw materials,diamines as crosslinking agent,anhydrous alcohol as dispersant and introducing hydroxyl groups to the molecular chain of polyaspartic acid.The effect of factors such as molecular weight of PSI,reaction temperature,amount of crosslinking agent,ethanolamine and anhydrous alcohol on water absorbency were investigated.Results show that the water absorbent ability of HPASP were 804g/g for dist... |
