【摘要】With acrylic acid as modifier monomer, N,N'-methylene-bis-acrylamide as crosslinker,and Potassium persulfate as initiator,super absorbent resin was synthesized by grafting copolymerization of the acrylic acid and cellulose from wheat straw after pretreatment. The effects of initiator does, cross linker dosage, monomer dose, and neutralization of acrylic acid on water absorption of resin were studied. The water absorben-cy of resin obtained under the optimal synthetic conditions was both large and rapid.%以小麦秸秆为原料,经预处理得纤维素后,以N,N’-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,采用水溶液聚合法制备了纤维素接枝丙烯酸的高吸水性树脂,探讨了引发剂用量、交联剂用量、单体丙烯酸用量、丙烯酸中和度等因素对吸水率的影响.最佳条件下制得的树脂不仅吸水量大,而且还具有吸水速率快的特性. 【总页数】3页(13549-13550,13552)
