Title: Synthesis of montmorillonite /poly(acrylic acid) super absorbent resin
Abstract: Alkylammonium ion was used to dispose sodium type montmorillonite(Na-MMT) to prepare organic-montmorillonite(OMMT).Montmorillonite/poly(acrylic acid)(MMT/PAA) nanocomposites were synthesized by the method of intercalation.The structure of the nanocomposite was characterized by FTIR and X-ray diffraction.The effects of the amount of OMMT,initiator,crosslinker and size of nanocomposites on the absorbency of nanocomposites were investigated.The results show that the intercalation is successful.Montmorillonite disperses in copolymer molecules at nano size after copolymerization and the absorbency of the nanocomposite is much higher than that of the pure PAA.The highest absorbencies of nanocomposites for distilled water and saline water are 1200g·g~(-1)(and 121g·g~(-1)),respectively.
