摘要：

In order to develop an eco-friendly polymer, a novel super-absorbent polymer was prepared by graft copolymerization of acrylic acid (AA), acrylic amide (AM) and dimethyl diallyl ammonium chloride (DMDAAC) onto the pretreatment wheat straw (PTWS). The molecular structure of the super-absorbent was confirmed by FTIR. The factors that can influence absorbencies of the super-absorbent resin (SAR) were investigated, such as weight ratio between the monomers, the ratio of PTWS to monomers, the amount of initiator and cross-linker, temperature reaction time and neutralization degree of AA. The SAR has the water absorbency of 133.76 g/g in distilled water and 33.83 g/g in 0.9 wt.% NaCI solution. (C) 2010 Elsevier Ltd. All rights reserved.
