摘要

以棉浆粕为基材

硝酸铈铵／HNO

为引发剂

甲基丙烯酸丁酯（BMA）为接枝单体

脂肪酶为催化剂

′-亚甲基双丙烯酰胺为交联剂

采用悬浮震荡接枝聚合反应制备了纤维素-BMA 接枝聚合吸油材料。采用红外光谱、X 射线衍射、扫描电镜、热重、差热等手段对产物结构进行了表征

考察了棉浆粕的引发及其后的接枝聚合反应

得到脂肪酶催化合成纤维素-BMA 接枝聚合吸油材料的最佳工艺条件为：棉浆粕用含有铈粒子的0.15mol／L 的HNO

水溶液

在45℃活化处理2.5h 后

在脂肪酶催化剂下

与BMA 发生接枝聚合反应。反应物质量比为纤维素／引发剂／单体／脂肪酶／交联剂＝1／0.03／1.5／0.02／0.02

反应温度50℃

反应时间 24h。在上述工艺条件下

所得纤维素-BMA 的接枝聚合物有较高的接枝率及理想的吸油性能。

Abstract

The cellulose-poly (BMA) graft copolymer oil absorption resins has been synthesized from butyl methacrylate modified cotton pulp (cellulose) which initiated with ceric ion /HNO

solution by shake graft copolymerization using porcine pancreatic lipase as catalyze

′-methylene-bisacrylamide as crosslinker.Structure of the cellulose-poly (BMA) graft copolymer was characterized by means of FT-IR、XRD、SEM、TG、DSC etc.Effects of the process of initiating cotton pulp and graft copolymerization condition were investigated.The ideal cellulose-poly (BMA) graft copolymer oil absorption resins could be prepared when the cotton pulp initiated with 0.15mol/LHNO

solution of containats ceric ion at 45℃ for 2.5h

then reacted with BMA by using porcine pancreatic lipase as catalyze

′-methylene-bis-acrylamide as crosslinker.Under the optimal conditions of m (cellulose): m (initiator): m (monomer): m (porcine pancreatic lipase): m (crosslinker) =1∶0.03∶1.5∶0.02∶0.02

50℃ and 24h

the graft yield and oil pick-up abilities of the synthesized cellulose-poly (BMA) graft copolymer oil absorption resins are choiceness.
