摘要

以丙酮为溶剂，以三乙胺（TEA）中和2-丙烯酰胺基-2-甲基丙磺酸（AMPS），合成了阴离子带不饱和键的AMPS-TEA可聚合离子液体，采用差示扫描量热（DSC）、傅立叶变换红外光谱（FT-IR）、核磁共振技术（

H-NMR）表征该离子液体；以过硫酸铵（APS）为引发剂，以N

N’-亚甲基双丙烯酰胺（NMBA）为交联剂，AMPS-TEA与丙烯酰胺（AAm）在水溶液中共聚，合成了Poly(AMPS-TEA-co-AAm)凝胶，研究了该凝胶的吸收行为.结果表明，AMPS-TEA的玻璃化温度为-59.4 ℃，Poly(AMPS-TEA-co-AAm)凝胶吸水可达218 g/g，吸收二甲亚砜可达68 g/g，并对1-丁胺、甲醇、乙醇、N-甲基吡咯烷酮等多种有机溶剂具有超强吸收作用.提出离子液体完全由阴、阳离子组成、处于完全电离状态，是可聚合离子液体的交联共聚物对有机溶剂具有超强吸收作用的关键原因.

Abstract

AMPS-TEA polymerizable ionic liquid was synthesized by neutralization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) with triethylamine (TEA) in acetone followed by evaporation of the solvent; DSC

FT-IR and

H-NMR were used to characterize the ionic liquid; by using N

N′-methylenebisacrylamide (NMBA) as a crosslinker

and ammonium persulfate (APS) as an initiator

poly(AMPS-TEA-co-AAm) gels were synthesized by aqueous copolymerization of AMPS-TEA and acrylamide (AAm)

the super absorbency for water and a variety of organic solvents of the gels was investigated as well. The results show that when the glass transition te

mperature of AMPS-TEA is-59.4 ℃

poly(AMPS-TEA-co-AAm) gels show super absorbency for both water (218 g/g) and a variety of organic solvents such as DMSO (68 g/g)

methanol

ethanol

and so on. It is suggested that the reason for super absorbency for organic liquids is dissociation of the ion pair of the ionic liquid irrespective of the liquid environment.
