摘 要: 利用麦秸秆、丙烯酸、丙烯酰胺和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为原料,通过接枝共聚合成高吸水性树脂。对影响反应的因素,如麦秸杆用量、单体丙烯酸、丙烯酰胺、DMC的用量和配比、引发剂及交联剂用量、丙烯酸中和度等进行了详细研究,得到了最佳制备工艺条件。制备的两性高吸水性树脂吸蒸馏水达853 g/g、吸生理盐水为118 g/g。 Superabsorbent polymers (SAPs) were prepared from wheat straw cellulose (WSC) , acrylic acid (AA), acrylamide (AM) and [2-( methylacryloyloxy)ethyl] trimethylammonium chloride (MAETAC) through graft copolymerization. Factors affecting water-absorbent capacity of SAPs, such as monomers ratio, WSC dosage, contents of initiator and crosslinking agent, and neutralization degree of AA were investigated and discussed in detail. Amphoteric SAPs, with absorbent capacity of 853 times their own weight in distilled water and 118 times in 0.9 % saline solution under optimized synthesis condition, were obtained.
