Abstract: A material with high water absorbency composite of cellulose and bentonite and acrylic acid was synthesized in aqueous solution.Mass fraction of cellulose,bentonite,initiator,cross-linker,acrylic acid neutralization degree and temperater were investigated.The results showed that optimal synthesized conditions(based on totalmass of reaction system) are: mass fraction of bentonite 15%,cellulose 2%,initiator 0.8%,cross-linker 0.04%,acrylic acid neutralization degree 80% and temperature 80 ℃.The absorbency was ...
